Motor Space heater size and terminal box according to NEMA standards
Motor Space heater size and terminal box according to NEMA standards
(OP)
In NEMA 01 is specified that "For machines rated 601 V and higher, accessory leads shall terminate in a terminal box or boxes separate from the machine terminal housing. What about lower than 600V? Is a terminal box required by NEMA for space heater leads? Is there a table with space heater size related to motor size in NEMA standards - it should, but I don't know where to look.

One additional thing is to check local and industry requirements. I do recall we had one nuclear safety related 460vac motor located in EQ harsh environment where plant licensing documents specifically required space heater and rtd leads routed through separate terminal box from main leads I can't phathom the original technical basis for that requirement, but as we investigated we found it was not something we could deviate from and we ended up doing a lot of rework to get our replacement motor to conform to the requirement.
