Well, it’s safe to say that since the last issue of Electrical Business, a lot has changed in the world.

As of the writing of this editor’s note, I’ve now been working from home for the last five weeks. While I am grateful for the fact that our governments and employers are taking the threat of COVID-19 seriously, I’m sure I’m not the only one finding it slightly difficult to adjust to our “new normal”.

While in most parts of Canada, electrical industry workers are considered essential and continue to work as usual, the risk of infection remains. That’s why I encourage everyone to take the government’s stance on social distancing and personal protection seriously, especially if you continue to work around others amid the pandemic. Your safety is paramount.

As many of us continue to be in lockdown mode, what better way to pass the time than paging through this issue of the magazine?

For this issue, I had the pleasure of speaking with a number of industry associations to discuss how COVID-19 is impacting business across the country, the fears contractors may be facing, and how employers plan to bounce back. You can find that article on page 10.

This issue also includes an article on unsafe electrical products, such as lighting that doesn’t meet the CE Code, still being available in some big-box stores on page 18, and information on the risk of contracting COVID-19 when sharing arc flash personal protective equipment (PPE) on page 20.

Also, this is where we say goodbye. Effective May 1, I’m moving onto another publication within Annex Business Media’s family. But fear not! You’re in good hands, as Anthony Capkun will be donning his editor hat once more to lead the magazine from the front lines as Publisher-Editor.

It was a pleasure providing you with news and information on this fascinating industry for the past several months. Thank you for reading each issue, writing to me with your thoughts and comments and, in general, being a fantastic audience.

Wishing you all well!

Ontario Power Generation’s 3D printers produce face shields to protect health-care workers.

OPG contributes PPE to healthcare facilities amid COVID-19

Ontario Power Generation (OPG) is using 3D printing technology to produce plastic face shields to address the growing need for personal protective equipment (PPE) for frontline healthcare workers amid the COVID-19 pandemic. OPG has partnered with Ontario Tech University in Oshawa to fast-track the production of face shields. OPG received approval from Health Canada to produce the shields.

“We have a lot of innovative and passionate people on our X-Lab team and I want to thank them for thinking outside of the box in anticipation of a medical supply shortage in the province,” said Ken Hartwick, OPG’s president & CEO.

OPG’s X-Lab innovation hub is now producing the headband piece used in the assembly of the face shields, and has secured materials for the plastic visor and adjustable elastic strap through OPG’s vendor partners.

Following the province’s request to innovate, businesses such as Protagon Display Inc. and Filaments.ca supplied material to develop the face shield.

The first batch of 200 face shields was expected to be shipped to Ontario’s Ministry of Health on April 8, with a plan to increase production to 500 units per week. The ministry will then distribute the shields to hospitals, long-term care homes and any other

essential healthcare providers in the most-needed areas of the province.

In addition, OPG has committed to donate 17,500 Tyvek protective suits to the province, which were part of its inventory for nuclear workers, and 500,000 surgical masks and 75,000 N95 masks that the OPG donated to the province in early April, in response to the growing shortage of PPE in hospitals and healthcare facilities across the province.

RESCON releases best practices for construction sites amid COVID-19

In response to the COVID-19 pandemic, the construction industry released a best practice guide and urges all employers to follow it during this time so construction sites can continue to operate safely.

The best practice guide includes seven safety recommendations developed by health and safety experts in Ontario’s construction industry and endorsed by labour and management representatives. They come from a document called “COVID-19: What you need to know about Health and Safety and Working On-Site.” The recommendations include:

1. Maintain good personal hygiene: Avoid touching face with unwashed hands. Cough and sneeze into elbow or a tissue and wash hands often.

2. On-site sanitation: Provide access to more hand-wash stations with soap and water, washroom facilities, commonly touched surfaces or areas (hoists, site trailers, door handles, equipment or residential units), and an increased cleaning schedule.

3. Practise physical distancing: Stagger start times, breaks, lunches, total number of people on site and coordinate pinch points, including hoists and site trailers, to keep people safely apart. Limit unnecessary on-site contact between workers and outside service providers.

4. Communicate policies: Employers must ensure everyone on site has a clear understanding of roles and responsibilities in health and safety. Policies must be posted and communicated to all employees, contractors and trades, including

According to Aitkin, ECAO members are focused on preparing for the “new normal” following this pandemic. “The bulk of what we are seeing is training that relates to COVID-19, anticipating a second or third wave, and coming out of this stronger and more prepared as an electrical contractor,” he says.

COVID-19 fears

Some contractors that are still on the job are worried about contracting COVID-19 while at the workplace. Sell notes that “the social distancing requirement affects different workers in different ways. Workers with young families or caring for elderly parents are more reluctant to continue working due to fear of infection.”

“Calls from individual workers to WorkSafeNB seeking guidance have increased dramatically,” adds Ellis. “In most cases, WorkSafeNB has been referring anxious workers back to their employers.”

Electrical workers employed by ECAO members are themselves members of the IBEW, says Aitkin. “Where there may be fear, we work with the IBEW/CCO to ensure that these fears are thoroughly investigated and dealt with. Further, ECAO fully supports the recommendation of the IBEW/CCO to their members that workers should not be put into a position to perform at a site that they do not feel has the proper COVID-19 (and, of course, all health and safety) protection.”

As for how electrical contractors in New Brunswick are faring emotionally, Ellis says most of the ECANB’s members seem to be concerned, but not overly frightened for the short term, and are cautiously optimistic for the longer run. Meanwhile, in Alberta, Barnett says members are uneasy because they’re unsure how long the halt to business will last.

Although the turn of events related to COVID-19 have been shocking, to say the least, Aitkin presents a positive message for the future, one that all contractors can surely relate to.

“I have not been associated with a group as strong, practical, caring and adaptable as the ECAO.Yes, they are facing a threat. However, like all of the threats faced in the seven decades of this association, I am confident that our community will come out of the pandemic even stronger, more united and with greater resolve than when we entered this time,” he says. “As a very resilient community, our members, labour partners and industry partners are collectively ‘rolling up our sleeves’. We’re resolved, not resigned.”

“Long term, there is work on the other side of this,” McMillan adds. “We just need to get through it safely.”

General use snap (light) switch bonding

Questions have been asked if a general-purpose snap (light) switch that includes a bonding terminal is permitted to be bonded to an outlet box without a bonding conductor.

Canadian Electrical Safety Code (CE Code) Rule 10612 3) requires a bonding connection to be made at every non-metallic outlet box for any device that requires connection to a bonding conductor. For any device that has a bonding terminal and is installed on a metallic outlet box, Rule 10-612 5) requires a bonding conductor to be installed to bond the device to the enclosure. Subrule 5) is a change in CE Code 2018 with the rewrite of Section 10. Since the previous 2015 CE Code had specific requirements for bonding jumper for receptacles only, this change raised some questions regarding light switch bonding.

approved, and will appear in CE Code 2021 (typically published by CSA on Jan 2021 and effective in Ontario by 2022) as follows:

“CSA C22.2 No. 42 General use receptacles, attachment plugs and similar wiring devices, requires that receptacles be connected directly to a bonding conductor. For some other devices, such as switches, the bonding connection is permitted to be made via the mounting screws to the device enclosure. CSA C22.2 No. 18.2 Non-metallic Outlet Boxes requires that the mounting screw termination point of a device enclosure be electrically connected to a bonding means within the non-metallic device enclosure. Installers should consult the manufacturer instructions for proper installation of wiring devices.”

A recent approved amendment to Rule 10-612 for the upcoming 2021 CE Code will clarify that some devices, such as a general use snap (light) switches, will not require a bonding conductor to the outlet box. Manufacturers confirm that a general use snap switch, certified to CSA C22. 2 No. 111, can be bonded to a metallic or non-metallic outlet box via the mounting screw or yoke. Based on standards testing, metallic and non-metallic outlet boxes are required to provide a bonding connection at the mounting screw termination point.

A new Appendix B Note to Rule 10-612 3) has been

Therefore, for general use snap switches that include a bonding terminal, a bonding conductor is not required to satisfy Rule 10-612. The screws and the yoke mounting the switch to the outlet box enclosure also meets requirements of Rule 10-612 based on certification requirements.
