bankruatsteve Posted July 20, 2016 Share Posted July 20, 2016 Sure. The top photo appears to be a unit without RCD protection which is typical for the AC, water pump, outdoor lights, like that. Link to comment Share on other sites More sharing options...
Crossy Posted July 20, 2016 Share Posted July 20, 2016 Is the sub-unit fed from the protected side of the RCD in the main unit? Yes - Safe No - Less safe, but possibly not a hazard, what does the sub-unit feed? Link to comment Share on other sites More sharing options...
