Lighting relay control
The GTD20A emergency lighting relay control device works in conjunction with an auxiliary generator or central inverter system to power designated emergency lighting loads up to 20 amps regardless of local switch position. The GTD20A acts as either a switch bypass or transfer device and is not limited to emergency lighting applications. It provides multiple wiring options and works with fluorescent, incandescent and HID lighting.
