Chris Hobson Posted July 3, 2015 Share Posted July 3, 2015 I cannot believe that when I ask an Electrical Wholesaler for a DC isolator switch and they send me a stove switch. ___ 1 Quote Link to comment Share on other sites More sharing options...
SilverNodashi Posted July 3, 2015 Share Posted July 3, 2015 That's probably because they don't (yet) know what it is that you're looking for. Most electrical wholesalers got training with AC equipment. DC is "foreign" to most of them. flatfourfan 1 Quote Link to comment Share on other sites More sharing options...
Mike Posted July 3, 2015 Share Posted July 3, 2015 and most do not stock DC breakers & isolators Quote Link to comment Share on other sites More sharing options...
Buks Posted July 5, 2015 Share Posted July 5, 2015 I'm not sure what voltage you want the isolator for, but CBI electric have a whole range of breakers for 80 volt. A CBI accredited re-seller should have a catalog that you could check out! Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted July 5, 2015 Author Share Posted July 5, 2015 HI Buks The max voltage is 129V DC and the max amp would be 36A. So either a breaker or an isolation switch would do. The PV home runs are fused in the combiner box. Chris Quote Link to comment Share on other sites More sharing options...
pwallace10 Posted August 13, 2015 Share Posted August 13, 2015 ...also more that when they realise what you ask for and know its not common, they load the price. I bought all my DC trip switches from Feoo, got onto then via Alibaba, you can pay using PayPal, a 100Amp DC trip switch double pole was 33 USD, the DC Fuse holder plus a 10 Amp fuse was 1.79 USD, 10 Amp DC trip switch was 2.51 USD I think Peter Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted August 14, 2015 Author Share Posted August 14, 2015 Hi Peter Have you imported a lot of stuff. I bought 2 specialised switches in June and they are yet to arrive. Chris Quote Link to comment Share on other sites More sharing options...

Most electrical wholesalers got training with AC equipment. DC is "foreign" to most of them. My local supplier has been trying to get on board with the whole DC lark and while he's far behind what I consider to be acceptable, he's at least making an effort. I had to go to communica to get hold of a 12v day night switch though. Chris Hobson 1 Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted August 25, 2015 Author Share Posted August 25, 2015 This post dates from a stage when I needed 1 component to complete my installation. I am sure everyone knows the feeling I needed that component NOW!. My wife went to EL and after I had phoned and asked whether they had DC switches in stock I received the above. My local supplier is actually sharp but we have a long supply chain to Graaff-Reinet so thing take time. He has come up trumps with strange things like 6 pin RJ11 connectors and AC contactors with DC coils. Quote Link to comment Share on other sites More sharing options...

Chris Hobson Posted August 25, 2015 Author Share Posted August 25, 2015 Thanks to SuperDIY I now know a 6pin RJ11 is a RJ12. It helps knowing what to call the thingie-ma bobbie that you saw at your mate's place that would work perfectly in your installation. I think half the local supplier's frustration is having farmers trying to describe components. ___ 1 Quote Link to comment Share on other sites More sharing options...
