Hello, I am currently installing a back-up lighting system (48VDC, ~7A steady state) for a local power company substation, based on their prints. They have similar systems in other substations and have had problems with the switches burning out quickly. It is a simple system, (5) 48VDC 60Watt incandescent bulbs controlled by (2) 3-way switches. I am finding that this is a tough load for a switch to carry and I am having a hard time finding a capable toggle. I understand that a lamp load appears as a near-short on powerup. I have located an industrial 30amp (277VAC) 3-way switch with "large silver cadmium-oxide contacts" and that may be sufficient, but I am not certain. Any recommendations as to switches (SP/DT or DP/DT), inrush current limiters, or other ideas would be much appreciated. Thanks all you smart guys!
