Re: DC rated switch question
Did you try Eaton or Honeywell websites? Do you know the amp rating?

20 amp breakers. I haven't looked there yet. Looked at Leviton and Hubbel.

Re: DC rated switch question
The lighting is coming off a GE Lighting Control Panel. Panel contains xformers and a rectifier. Input is 208VAC 3Ph and output is 115VDC. Switches are located in an MRI suite. Original electrical contractor put in standard commercial 20 amp 120/277V rated toggle switches. Problem is that DC arcs longer than AC and damage, due to heat, occurs pretty quickly. One switch stopped working all together while the other is still arcing with a nice greenish light(copper/brass). I would hate to tell the guy he needs a pair of contactors up above the ceiling when all he thought that was needed was a new $5.00 switch.
