Hi Everybody,
I am looking for some advise or comments on what I know about CSA components and protection methods. Without having the CSA documents or access to an inspector in Canada, pretty much until they make the trip to come in and do the assessment.
(This is not including the PSR evaluation) I am sure I will have to make it control reliable for that, I think?)
I know I do most of these items already but the Fuses VS other choices(ie.Circuit breakers, MMP) is my main concern.
What I think I know about CSA (is this a correct assumption?)
1. All 3 phase motors should have overload and fused short circuit protection. (Does this mean I cannot use supplemental circuit breaker protection before the contactors?)
2. Transformers/Power supplies: Both primary leads must be Fused .The hot line of the secondary must be Fused
3. Ground the 0V of a control transformer.
4. Label all fuses with the replacement size and type
5. Any primary/Branch Circuit protection must be fuses instead of Circuit breakers.
I know I may be missing items in this but I am trying to avoid having to replace all my breakers and wiring after the assessment.
Thanks for viewing.
