8.1 Contact Cable Hookup
A typical, contact cable connection to a circuit breaker is shown in Figure 3.0. Red and black
clips are connected across the circuit breaker contact phase A, B and C.
A typical circuit breaker with series contacts is shown in Figure 4.0. In the below example,
the circuit breaker has 2 contacts in series per phase. Contact timing channel 1 and 2 are
used in the illustration.
NOTE
It is advisable to ground one side of the contacts for most testing purposes. If a breaker
is floating or ungrounded, ensure that the contact channel inputs are protected against
static discharge.
