A question for any power control experts

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

I'm wanting to run a current limited 220 volt mains supply to yurt from a pure sign wave inverter housed in a separate structure. I wanted to know the safests cuircuit breaker to use, and I wanted to know if it is possible to get a self reseting trip that limits the maxium power drain to 3 amps. The inverter is correctely earthed using a earthing rod. I do have knowledge of power control as I was Marconi trained many many years ago, it's just my knowledge is a little rusty.

	I suspect a tent will need enhanced protection similar to marquees as the risk of shock and moisture ingress is greater outdoors. (rcd+mcb, or RCBO). For safety reasons of course this protection must not be self resetting. If you then want to add an overcurrent trip for power rationing purposes, in addition to the main circuit protection then something like a current operated relay with reset timer would probably be the cheapest route. This is the sort of circuit that really needs an NICEIC contractor and regular test certificate.
