Peoples. Really scratching my head on this one. Wired up as per labelling and my camper sockets showed reverse polarity via my LAP socket tester. Rechecked all my connection in case senility had kicked in but everything correct. Disconnected inverter 240v output and put LAP directly on to inverter socket and it registered no earth! Checked my cabling again including grounding the extra earth all fine but still getting no earth...
Decided to put a plug on rather than hard wire and tested again... guess what.. same fault on sockets... neutral live polarity issue according to my LAP Tester.
Wanted to protect inverter socket i fused the battery input and it blew 30A fuse when I switched on camper microwave. 750w draw 500W microwave.. I am fairly technically competent with 30 years as electronic engineer but this is beating me...
Any reasonable suggestions?
