Instruction for the

Cutler-Hammer Type MPCV

Network Protection Relay

The COMPLEX TAP — a Short Run cable which physically

“Ts” off a Main Run and may have “sub Ts”. No EOLTRs are

used within a Complex Tap.

Requirements:

1. The total length of cable in the Complex Run must not

exceed 200 feet (61 m).

2. The total number of IMPACC devices must be equal

or less than 64.

3. There are three levels of subtaps allowed with a

restriction of 4 feet (1.2 m) on the third level.

Figure 10. Complex Tap

The MAIN NETWORK — consist of the Main Run connected

to a MASTER as well as all the cabling in Simple Taps and

Complex Taps connected to the Main Run.

The SUBNETWORK — consist of the Main Run connected to

a SUBMASTER as well as all the cabling in Simple Taps and

Complex Taps connected to the Main Run.
