Elementary motor wiring
Elementary motor wiring
(OP)
I have a confidential project involving a 2hp 3 phase motor.
The motor will be inside a fiberglass housing. What type of wire must I use inside the housing? Must I have a junction box where the wires terminate?
My concern is based on the fear that thre will not be enough room to run heavy cable in the not-too-big interior.

RE: Elementary motor wiring
what is your voltage supply? 230, 460 etc.

One 3 Phase 2 HP Squirrell Cage Motor will drawn at 230 Volts 6.8 Amperes at Full load. Normally this small motors use Y or 2Y, Then you will need only four wires, 3 for phase and 1 for earthing. Use 4 wires EXAR 3562 AWG 22 -600 volts Class F(150 Grades C),manufactured by CHAMPLAIN CABLE.I don´t think you need the junction box because you could open a small hole on the fiber glass housing and pass the power wires from outdoor to indoor housing and then connect with the motor, I think you could remove the motor´s conection box.The housing hole can be sealed and closed with Silicone compound.

RE: Elementary motor wiring
Large cables lead me to assume that there may be voltage drop "distance from the 3ph 230/480 volt source". If this is the case you could install a Junction Box some where close to/on the outside of the (fiberglass housing). At that point you could use 1/2in. flex to your motor connection box and use smaller single conductors (#14Awg) for your connection at the Motor. Again I'm not sure of your particular configuration but I don't think you would want an installation with out installing some type of raceway (Flex/Conduit) for your Motor supply cables/conductors. !! SAFETY!!
Again, Corrections Welcome
