PROTECTED EQUIPMENT 4 G 1 U W BAC SOURCE M-RESTER BREAKER Be sure to install the breaker. PROTECTED EQUIPMENT ■ Single phase 2-wire ■ Three phase 3-wire ■ Single phase 3-wire N 4 G 1 U V BAC SOURCE M-RESTER BREAKER Be sure to install the breaker. PROTECTED EQUIPMENT GROUNDING M-RESTER PROTECTED EQUIPMENT GG CROSSOVER WIRE GROUNDING (100 ohms or less) A crossover wire between M-RESTER ground and ground or metallic housing of equipment is required for protection. If the protected equipment has no ground terminal, ground the M-RESTER only.
