Is there anything in NEC that talks to max number of 480V receptacles you can load on single branch circuit? I’ve seen up to 4, 60A welders on a 100A circuit.

I'd like to think it was not permissible due to the fact that it is a welder allowance and nothing assures other type equipment might not be plugged in. Perhaps another member can correct my interpretation,

If the recepts are internally fused. I believe you can put more than 2 on a circuit
