INSTALLATION AND SETUP

(7) The equipment-grounding conductors used between the GC Controller and the copper-clad
steel ground rod must be sized according to the following specifications:
- length, 15 feet or less - AWG 8, stranded, insulated copper wire
(4.6 meters)
- length, 15 to 30 feet - AWG 6, stranded, insulated copper wire
(4.6 to 9.1 meters)
- length, 30 to 100 feet - AWG 4, stranded, insulated copper wire
(9.1 to 30.5 meters)
(8) All inter-enclosure equipment-grounding conductors must be protected by metal conduit.
(9) External equipment, such as data printers, that are connected to the GC Controller should be
powered via isolation transformers to minimize the ground loops caused by the internally
shared safety and chassis grounds.
