Are these motor loads that are being powered off this panel?
NEC Article 430.102 (A) States: "An individual disconnecting means shall be provided for each controller and shall disconnect the controller. The disconnecting means shall be located in sight from the controller location."
This means that there must be a disconnecting means within site of each motor.
The receptacle and cord cap are within 5 ft. of the saws/grinders but the breaker box from which the power comes is located in another building.
Is the building where the motor loads are located on the same service as the building where your feeders are coming from
no, it's about 100 ft. away
Here is an idea, why don't you sell him on a 3phase disconnect that is accessible when you come through the wall?
The main breaker box has a 200 amp 3-phase in it.
then your feeders can be shut off in the building where they are supplying the utilization equipment
So come off the main breaker box, run through the wall into the back of a properly sized three phase disconnect then run out to the new panel.
He says he wants to use the receptacle and cap as the disconnecting means.
that's fine, he can do that. Did you see my solution above?
We are running from the main 800 amp 3-phase panel to this 200 amp 3-phase panel which is located in the attic area next to the building where the motor loads are located.
Does the breaker box have to be located in the same building as the motor loads are located?
Not really, but it would be safer to have a separate disconnect as I outlined above.
Is this installation going to be inspected?
There is no inspecter in our county
Ok, so it won't be inspected, correct?
Did you see my solution? Does that make sense?
The 120 volt circuits that come into the same area have no disconnecting means except for the cord/cap receptacle. Does this make a difference?
No, the way he wants it done is OK, according to code.
Okay. Thank you for your help.
How about a disconnect where you come through the wall? Would that make you feel better?
Right now a trip to Cancun would make me feel the best, but a disconnect coming through the wall is a good 2nd.
Do you provide free trips to Cancun with your answers?
I wish!!! I don't think I would choose Cancun though.....maybe Aruba.....:)
