Its 2022 UL508A is long dead in my opinion.We have a customer who wants to convert a pilot plant from US standards to Canadian standards so it can be shipped to a potential Canadian customer.
Does Canada accept UL508a? I thought it had to be CSA 22 something.
I am told the cul sticker is something we are allowed to apply. It's not real clear what differences there are if any.Bob,
Talk to your UL rep. You can add a cUL listing to your 508A program, making you compliant to CSA standards and cUL is acceptable in Canada. There is very little that is different, it’s mostly differences in grounding requirements. When I had my panel shop 20 years ago, the added listing capability cost me $1,000 plus another inspection fee. I’m sure it has gone up, but is not likely an unbearable cost.
One thing I remember was that for metal enclosures, Canada required a ground wire bonding the door across the hinge, but for regular UL it was not necessary.I am told the cul sticker is something we are allowed to apply. It's not real clear what differences there are if any.
