6.6 GCP300 Panel (Optional)
The GCP300 is an option that provides AC Voltage and AC current analog gauges with the GSC300
together in an enclosure.
AC Voltage and Current Hookup
The below drawings explain how to connect to the current transformers and AC voltage lines to the
GCP300 in a 3 phase setup. Referring to Figure 7 the hookup is as follows:
1. The neutral from the generator connects to the NEUTRAL terminal.
2. Phase A, B, and C from the generator connects to the L1, L2, and L3 terminals respectively.
3. The white wires of the current transformers connect to the A1 (CTP1), A2 (CTP2), and A3
(CTP3) terminals for Phase A, B, and C current sensing respectively.
4. The black wires of the current transformers connect to the three COM terminals. The COM
terminals are all connected together internally so order is not important.
