Circuit B
The ground conductor in Circuit B (to the host terminal) is an isolated,
insulated ground – it must be isolated from the outlet box for the host
terminal. The circuit breaker in the power conductor of Circuit B is
optional. If used, it should be near the operator and recessed.
Circuit C
The power conductor in Circuit C (to the NCR 7870) should include a
15 Amp circuit breaker located near the operator. The circuit breaker
should be recessed to prevent being accidentally switched on or off.
Note:
The outlet boxes for the NCR equipment must be isolated and
insulated from the ground conductor, convenient to the equipment,
readily accessible, and labeled as exclusively for use with NCR
equipment.
