For fixed electric space-heating equipment such as an electric furnace, the branch-circuit conductors and the overcurrent protective devices shall not be less than ___ of the total load of the motor(s) and heater(s).

An overcurrent device shall not be less than ___ for continuous loads on feeders.

The rating of a branch circuit is based on the rating of the overcurrent device.

Connected loads can exceed the branch-circuit ampere rating.

For a continuous load of 40 amperes. The minimum overcurrent device rating and the minimum conductor ampacity is:

If a feeder supplies a continuous load of 20 A and a noncontinuous load of 10 amperes. The minimum overcurrent device rating and the minimum conductor ampacity is

No time delay fuse for the protection of wound rotor shall have maximum rating of:

Dual element time delay fuse provided for the protection of synchronous machine shall have a maximum rating of:

If the conductors of the branch circuit supply a number of receptacles for cord-and-plug connection of portable loads having an ampacity of 55 amperes could be protected by a 60-ampere overcurrent device.

Multiphase (other than delta-delta, 3-wire) transformer primary conductors shall not be considered to be protected by the primary overcurrent protective device.
