Electrical Industry Canada: Arc Flash, Shock Hazard, & Fire Safety - 20

Why is arc fault breaker code still in effect for appliances with
motors, especially washers, which trip very oſten? Is it possible
to eliminate this one? This is a dedicated circuit anyway.
There's been a lot of discussion on this, we've engaged with Electro-Federation
Canada (EFC), which is the association of manufacturers.
They are noticing arc fault breakers are tripping some washers and
microwaves. "
An AFCI device is an important safety device that is intended to
prevent electrical fires on both sides of the walls. C22.2 No. 270-16:
Arc fault protective devices has over 20 tests AFCIs must pass regarding
unwanted tripping.
According to Electro-Federation Canada, they are working with
appliance manufacturers (primarily for microwaves and washing
machines) whose products are causing unwanted tripping.
There is a bit of challenge there, Brown noted, because the products
are changing every 6-months. " The breaker design may only be
changing every year. Every time they add new signatures, a new
product comes out and it doesn't get added to the breaker. "
Brown noted that in ESA's discussion with EFC, they've been working
with manufacturers to get these signatures added in at the time of
production, so that they aren't affecting this. " This is an ongoing
process, I know that probably isn't an easy answer to swallow, so there
are other options when you run into problems. "
Brown noted that given the importance of AFCI devices, EFC is not in a
position to say you don't have to install them, " So, you should follow
the code and install the device. If you do have problems, it's required
that you do troubleshooting before you submit an occurrence. "

" In
general, the manufacturer will try to work with you to see if there's a
different firmware or troubleshooting they can do from the manufacturers
perspective. "
Can ESA accept a request for deviation to install a non AFCI
device on a dedicated circuit feeding 1 duplex receptacle once
the customer provides an email record that the manufacturer
has identified that they are dealing with the nuisance tripping
issue?
ELECTRICAL INDUS TRY CANADA
Yes, a deviation can be considered once the following conditions have
been met:
*An email record from the manufacturer of the affected AFCI breaker
has been provided to the ESA. First the issue must be reported to EFC
through this portal: https://esasafe.com/contractors/afci-nuisance-tripping/
*The
contractor declares there are not improperly wired circuits.
*The deviation form is signed by the contractor and homeowner.
Where are ground bushing (bonding bushings) required in
residential wiring?
Below are some of the most common locations:
*10-604 Bonding continuity for service equipment: Services with
metallic wiring methods.
*10-606 Bonding continuity at other than service equipment and
12-3000 2) Outlet Boxes: Non-metallic enclosures with metallic wiring
methods.
" If it's a single conductor we typically say as long as it boded at one end.
If it was an armoured cable coming from a metallic box, we would be
okay, however if there were multiple connectors coming into a non-metallic
box then it would be required to be bonded together, " said Brown.
10-606 2) Bonding continuity at other than service equipment: Reducing
washers.
