(B) Receptacles.
(1) Single Receptacle on an Individual Branch Circuit.
A single receptacle installed on an individual branch circuit shall have an ampere rating not less than that of the branch circuit.
All this stuff is one one circuit?Thanks,
I know for a 40A range you can use a 50A receptacle, but this is a different scenario.
They have a bunch of portable water cooled chillers with 1HP motors that are installed cord and plug to a 30A twicktock. I am trying to determine if these are even permitted to be installed cord and plug.
I would rather just install fused disconnects and be done with it, but obviously they are asking why it has to be different than all of their existing equipment
They don't make a 40A 3wire grounded receptacle that I am aware ofWhy don't you get correct plug and receptacle???:blink:
No they are all individual branch circuitsAll this stuff is one one circuit?
They don't make any 40A receptacles at all up hereNJWVUGrad said:They don't make a 40A 3wire grounded receptacle that I am aware of
This doesn't sound like the kind of place that'll spend the money on thatjarhead0531 said:Depending on the exact use I bet that Hubbell makes something that would work, or another option is Meltric plugs. Go to the supply house and ask to see their hubbell catalog. I just picked up a 100A cord end and recept for a 15hp motor, pretty sure they will have something rated for 40A.
It's a motor compressor with 31.2 FLA ...I can size my ocpd up to 175%.ponyboy said:Well since they are motor loads with a 30+ fla I don't know why you've got them on a 40 amp breaker. Is 480 volt available in this place?
Sorry I didn't do the math. But anyways what voltage is itNJWVUGrad said:It's a motor compressor with 31.2 FLA ...I can size my ocpd up to 175%.
208/3 phaseSorry I didn't do the math. But anyways what voltage is it
So what does all the other stuff have to do with the circuit in question?No they are all individual branch circuits
Can they be wired for 480NJWVUGrad said:208/3 phase
Will you shut up with the voltage already. :laughing:Can they be wired for 480
That 50a receptacle should have conductors rated @ 50 amps too. You could put a 50 amp receptacle here, it would just have to be on a 50a circuit. Are these factory wired with the 30a twistlock?Thanks,

The wires are protected by the breaker, how does the receptacle figure in that?KGN742003 said:That 50a receptacle should have conductors rated @ 50 amps too. You could put a 50 amp receptacle here, it would just have to be on a 50a circuit. Are these factory wired with the 30a twistlock?
