[QUOTE="binky, post: 522670, member: 490"] all test gear is merely 'an indicator' but some are more accurate indicators than others... LOL! 3-4mA is too bad, if you find something showing a steady 30-40mA, or more, then it will have sufficed it's function. As I said before, it really is worth altering your set-up to get rid of the 300mA RCD and oush the RCd protection onto the submains / dist boards around the site. I encountered a similar set up many years ago whilst quoting for solar panels on a caravan site down Cornwall. I was glad not to get the job becuse the way the solar inverters start up is good at upsetting RCDs, and the site owner wasn't going to fork out for a complete new cable run of 300m, or interested in paying to change what he had. It made fitting the panels uneconomic anyway. [/QUOTE]
