I'm beginning to wonder if anyone what reads what I write.. I sent him an email with a link to the instructions/manuel to help prove that the external pumps were figured into the MCA. But my aguement is that in Mass we have changed 334.80 to this:
So in my install there is no thermal insulation and the amb. temp. is not above 86f . but if were and I did need to derate for temp ,.the temp rating I would get to start from is 90c or 40 amps ....so per that stupid note I do in fact have a "WIRE" rated for 40 amps ... What say any and all ????
Even without your local amendments you still have a conductor that must be sized for 60 deg, but you are allowed to use 90 deg values for derations. I did not comment on your initial mentioning of the local change because I did not see that it made any difference in this installation. The biggest change I see in the amendment is removal of the second paragraph of the NEC content. Most of the rest of how it is worded still has same requirements just worded differently. I question whether or not this is a good idea to remove the second paragraph. I have seen demonstrations of loaded (not overloaded) cables encased in foam insulation and the temperature gets suprisingly high inside that insulation, the more cables you encase close together there the more heat you can develop in there.
They wrote that section for good reason.
