Hello all,
We are an ag controls company that primarily works in the US.. In the last few months, we have gotten a surge of business from Canada and have a question to pose to those who may know..
The question I have is this: in Canada with ULc or CSA requirements, can we still use properly labeled multiple power source panels within the same electrical room (and line of site) as the load centers feeding these panels?
Explanation below:
In our industry, almost everything is redundantly powered and run from individual control circuits from multiple load centers.. (fans 1 and 2 come from panel A, fans 3 and 4 come from panel B, etc) Industrial style disconnects on the contactor panels and control transformers feed from line side power on unheard of except for imported european equipment.. (to get proper animal safety, one would need a complex set of multiple panels fed from multiple sources, etc) There can never be a single (or in many cases a double) point of failure (think disconnect, breaker, generator, service, transfer switch, transformer, fuse, etc) that deactivates the life support for these buildings. (Yes, all work on these systems is by definition "Hot work", as the animals won't take a break from breathing while we work..)
