Circuit breaker and power outlet balancing requirements

NEMA
If your equipment is mounted in a rack, the total number of circuit breakers required for your equipment is based on the current draw. You should not load a circuit beyond 80% of the rated limit for the circuit.

For example, if you have a 20A circuit, you should load it to no more than 16A of draw.
