Myarc Electric


Our safety program

The Management team at Myarc electric Ltd. Is committed to providing leadership and support in order to develop and maintain the health and safety of each and every employee within the company. With this in mind we have achieved our COR Certification.

What Is COR?


The Certificate of Recognition (COR) program shows that the employer’s health and safety management system has been evaluated by a certified auditor and meets provincial standards. These standards are established by Occupational Health and Safety (OHS).

To get a COR certification your business must first have a health and safety management system in place, and then have it successfully audited through a Certifying Partner.

How do we keep safe?


The prevention of work place injuries and illness is of the utmost importance, and as such it will always be given priority over production. We are committed to providing all safeguards required for continued employee health and safety in keeping up to date with the highest occupational standards.

With every project we undertake our HSE goal remains consistent and unchanged: zero incidents, zero injuries, zero damages and zero environmental damages, from start to finish!

With every new site, new day and new job task, we realize the potential for new and various hazards. We are always training our staff to manage these potential hazards, rather than ignoring them.  Every time new work starts a field level hazard assessment must be done.  This empowers the workers to assess the task and deal with the hazards before starting the tasks at hand. Following proper leadership from the management team everyone must participate, from the foreman to the beginners. Safety isn’t just talk; it’s a way of life, each and every day at home and on the job. We do this by not just telling our staff how to be safe, but by showing them and providing the proper tools and training. The management team believes that we can and will maintain a zero loss standard.

The importance of calling before you dig

Imagine you’re out digging on a job site or even in your own yard and you hit a power line. What are the possible outcomes? If you’re lucky, the fuse/breaker will pop and you’ll need to have the wire repaired by an electrician. Unfortunately, not everyone is lucky. What if you hit a 5kv line and get electrocuted? Or you hit the feed to your house causing a short circuit causing an electrical fire in your electronics in your home. (Yes it can happen. Stay tuned for our blog on short circuits)

What if you hit a gas line?

 Have you ever seen the picture of a field with a big hole in the ground and it’s all burnt? That farmer was using a post hole auger to build a new fence when he hit a high pressure pipe line 

The body was never found!

The body was never found!

All of the above can be avoided if you just call before you dig. In Alberta 1-800-242-3447 is the number. It might save a life.


Ok so you’ve called One Call, now what?

A few things you need to know

1.        Keep your One Call paperwork on site.

2.        It is only valid for 2 weeks.

3.        You still need to maintain a minimum distance when digging with machinery around the located services. If you need to dig inside that zone it might be best to call a hydro vac or grab a shovel.

4.        If you hit a line your first call is void and needs to be re filed with another locate request.

5.        If you hit a line you are responsible for the damages.


What do I do if I hit an electrical line?

If you hit an electrical line be very careful and follow your company’s safety procedures.

Who do you call to have the power turned off?

  •   If it’s in Edmonton, call EPCOR @ 780-412-4500
  •   If it’s outside of Edmonton, call Fortis @ 1-866-717-3113

Ok, once the power is off and it’s safe again, who fixes it? If it’s owned by Fortis or EPCOR they will fix it. If it’s a customer owned wire you need to call an electrician. 

Call Myarc Electric for 24 hour service @ 1-866-210-0293. We will come out and make the repair, have it inspected, and get you back up and running.

Once the Electrician is done they will call the provider and have power turned back on.

Even though One Call was called the excavator still hit the line. In the above picture you can see the repair done to a customer owned line. This picture was taken after inspection while EPCOR was on the way to turn the power back on.

Electrical safety for flooded homes

Electrical panel rusted away after a flood

Electrical panel rusted away after a flood


Electrical Safety Flooding forces homeowners to ask many difficult questions about water-damaged electrical equipment in their houses.

            • Can I use my appliances after they dry out?

• Are circuit breakers and fuses safe to use?

• Will I need to replace my electrical wiring?

Dealing with the aftermath of a flood can be difficult as much of the damage may not be immediately visible. The different contaminants in floodwater can create serious fire hazards if electrical wiring and equipment have been submerged in water. Even with professional cleaning and drying, sediments and toxins are difficult to remove. As families begin to clean up after a flood, there may be hidden electrical hazards. This is not a do-it-yourself project! Before beginning, have a qualified electrician check the house wiring, assess other damages and proceed with repair work. Then, follow these important safety tips:

• Do not flip a switch or plug in an appliance until an electrician tells you it is safe.

• Do not touch a circuit breaker or replace a fuse with wet hands or while standing on a wet surface.

• Do not allow power cord connections to become wet. Do not remove or bypass the ground pin on a three-prong plug.

• Do not remove or bypass the ground pin on a three-prong plug.

• Use portable ground-fault circuit-interrupter (GFCI) protective devices to help prevent electrocutions and electrical shock injuries.

• If electrical devices such as circuit breakers, fuses, GFCIs, receptacles, plugs and switches have been submerged, discard them.

• When using a wet-dry vacuum cleaner or a pressure washer, be sure to follow the manufacturer’s instructions to avoid electric shock.

• Portable generators emit carbon monoxide (CO), a poisonous gas that is colorless and odorless. For this reason, portable generators should never be used indoors or outdoors near open doors, windows or vents.

• Do not turn on damaged electrical appliances. Electrical parts can pose an electric shock hazard or overheat and cause a fire.


Replace or Recondition?


Some items may be reconditioned, while others will need to be completely replaced to protect you and your family. It is recommended that you allow an electrician or electrical inspector to guide the restoration or replacement of any electrical wiring or equipment. Corrosion and insulation damage can occur when water and silt get inside electrical devices and products. Water can also damage the motors in electrical appliances. Therefore, you should be prepared to replace:

• Circuit breakers and fuses

• All electrical wiring systems

• Light switches, thermostats, outlets, light fixtures, electric heaters and ceiling fans

• Furnace burner and blower motors, ignition transformers, elements, and relays for furnaces and hot water tanks

• Hot water tanks

• Washing machines, dryers, furnaces, heat pumps, freezers, refrigerators, dehumidifiers, vacuums, power tools, exercise equipment and similar appliances

• Electronic equipment, including computers and home entertainment systems


Safety tips for water-immersed Type NMD90 nonmetallic-sheathed cable, i.e., Romex®


Type NM-B nonmetallic-sheathed cable (commonly called “Lomex® ” in the industry) is Listed by UL for use in normally dry locations in accordance with the National Electrical Code ® (NEC ® ) under the product category “Nonmetallic-sheathed Cable (PWVX).” General Guide Information for this category can be found in UL’s Online Certifications Directory. Decades ago, the outer jacket of this cable changed from an impregnated, braided covering to polyvinyl chloride (PVC). In the mid-1980s, the internal conductor insulation went from a temperature rating of 60°C to a 90°C rating, and the required marking was changed from “Type NM” to “Type NMD.”

The older, braided jacketed version of this cable has less resistance to water penetration than the newer, PVC-jacketed version, and if subject to immersion, such as from flooding, the suitability for continued use is unknown. Any cable of this type that has been subjected to flooding should be replaced without question.

In general, cables with PVC insulation and jacket can withstand immersion in clean water for a short period of time without being damaged as long as the ends are not immersed. If the ends of the cable are immersed for any period of time, however, the internal paper wrapping around the bare equipment-grounding conductor will absorb and transfer the water into the cable assembly. The water may then start degrading the insulation or possibly corrode the conductors. If the cable comes into contact with contaminated water, the contaminants may also act on the insulation or conductors. Over time, failures can occur.

In a flooding situation, there is no way of knowing how long the cables were immersed in water, or what types of potentially corrosive substances may have been in the water that flooded the cables. After Hurricane Katrina it was widely reported that raw sewage and chemicals were in the floodwaters afflicting the Gulf Coast region of the United States. Nonmetallic-sheathed cable has not been investigated by UL for this type of exposure. Therefore, it is not possible for UL to state that cable in a particular installation is acceptable for continued use after having been subjected to the flooding. The safest approach is to replace any nonmetallic-sheathed cable that was immersed in water for any period of time during the flooding.

The devastation of a flood is enormous. As the contaminated waters recede, there may be even more threats to your personal health and safety. By taking basic precautions, you can help prevent many injuries. IAEI and CUL urge you to always put the safety of your family first.

Halloween Safety Tips

Reports say Halloween is almost as popular as Christmas for consumers who display indoor and outdoor decorations.

As you and your family prepare to celebrate Halloween with elaborate decorations, fun costumes, and candle lit displays, Myarc Electric offers the following electrical safety tips to help you and all your little trick-or-treaters remain safe.


·         Always select costumes, decorations, and accessories which are made from flame-resistant, flame-retardant, or non-combustible materials.

·         Instead of flame candles, use flashlights or battery-operated candles when decorating your home, including the lighting you use to light your walk paths, jack-o-lanterns, and other outdoor displays.

·         Be sure to carefully inspect each decoration before using it. Any cracked, frayed, or bare wires may cause a serious electric shock or start a fire, so be careful not to use damaged electrical decorations.

·         Make certain the electrical decorations you plan to use outdoors are actually marked “for outdoor use.”

·         Electrical cords can be a tripping hazard. Keep them out of high-traffic areas, including doorways and walkways.

·         Be sure to plug your outdoor decorations into circuits protected by a ground fault circuit interrupter (GFCI) to prevent electric shock.

·         Do not nail or staple light strings or extension cords. Nails and staples damage an electrical cord’s insulation, which can create serious fire and shock hazards.

·         Always use safety approved electrical lights and decorations. Check for approval by independent testing laboratories such as UL, ETL-SEMKO, or CSA.

·         Remember to always turn off your electrical decorations and put out any open flames before leaving your home or going to bed.

USEB 90 cable Installation Warning



ACWU 90 teck

ACWU 90 teck

As a Master Electrician, I have worked in the electrical field for over 30 years. It has been common practice to use USEB cable for underground electrical services into houses: this is an aluminum cable with two conductors, and a PVC jacket covering. We were recently called to a called to a home where we needed to remove the concrete driveway and dig down 7 feet into the soil and gravel to find the service – it had been blown apart. The cable had been installed into a sand bed and had no rocks pushing against it: and so I was left pondering. Why had it been destroyed?


Here is a broken USEB 90 cable in a 7 year old underground service notice the massive scrape   This service was located under a concrete driveway

Here is a broken USEB 90 cable in a 7 year old underground service notice the massive scrape

This service was located under a concrete driveway

We repaired the cable, using an approved method of cutting out the broken section and splicing the two halves back together. We called for an electrical inspection. The Inspector then informed me that in five years of inspections, he had seen this exact same scenario over forty times: he thinks that the cables had likely been damaged during installation and on high rain years, like this year, the water gets into the cable and destroys it.


So the question to consider is do we continue using USEB cable for a cheap install and deal with the aftermath later or do we upgrade to a protected cable like an ACWU cable (a cable that has an outer armor of aluminum)? When will our codes catch up to the problems we are having in the field? Please KNOW what kind of service you are getting on your home; be aware. The dangers of using a USEB cable that has been damaged can result in a loss of power, like our customer, or a house fire.

Air Conditioners and your Power Bill

Air Conditioners and Your Power Bill

Living in Alberta, we know all about the drastic temperature changes the region experiences throughout the year – from a bone-chilling -40 degrees in the dead of winter to a staggering 35 degrees and more in the heart of the summer. Canadians are built to withstand the extremes, but let’s not fool ourselves, sometimes we need a little help, and that’s why air conditioners were invented. An air conditioner is defined as a device that removes heat from the air inside of a building or vehicle, lowering the air temperature.


So how do these systems work?


There are three main parts to an air conditioner: compressor, condenser, and evaporator.  The compressor and condenser are typically located outside of the house, while the evaporator is inside. The compressor builds up pressure and forces the refrigerant towards the condenser as a hot gas. When the refrigerant leaves the condenser, it has cooled significantly and changed from a gas into a liquid. This liquid is then pushed out into the evaporator, where it undergoes one more state change, this time back into a gas. Air conditioners are equipped with fans, which blow this cooled air throughout the house. The warmer air floats back to the compressor to begin the process all over again. This continues until the room reaches the desired temperature.


Now, it’s time to consider the costs of being comfortable during the hot summer months. Along with the substantial upfront cost of the air conditioner, which can run up into the thousands, it uses a significant amount of extra power. According to Dyand Mechanical (June 2015), the most common type of an AC unit in Edmonton, AB is a 2 ton, 17 amp unit. If you ran this unit for six hours per day, the additional monthly power cost would be around $95.00, assuming a 12.7 cents/kwh cost of power. Depending on your lifestyle, only you can make the decision if it is a worthwhile investment.


If you decide to not invest in an air conditioning unit, fans are another great option. If you place them in your window during the night, they will pull the cooler air into the room. You can also darken rooms during the day with blackout blinds and take a cool shower before bed time. All of these will help you to stay cooler during the brutally warm days without the higher costs associated with air conditioners.
