Exam 19: Service Panel Trim-Out

A 120-volt branch circuit or feeder circuit supplying a dishwasher will require a __________ circuit breaker.

NEC Article __________ provides many installation requirements for overcurrent protection devices.

Explain what a hexagonal configuration on a plug fuse indicates.

Name an advantage to installing a multiwire circuit in residential wiring.

A fuse type that uses the same standard screw base as an ordinary light bulb and where the different fuse sizes are interchangeable with each other is called a(n) __________ fuse.

A(n) __________ fuse is enclosed in an insulating tube that confines the arc when the fuse blows and is available in either a ferrule or blade style.

When installing a two-pole circuit breaker to protect a two-wire Type NM cable feeding a 240-volt electric water heater, describe what needs to be done with the white conductor in the cable that will be terminated at the breaker.
