what if i just have my electrican regulate my home caravan socket im having him put in to 15amp and 230v...
I'd have a read of this
the "15A" plugs are not good for 15A continuous for hours on end, they overheat. Hence the need for the chunkier plug. If you look at the 15A vs 16A rated plug you can see the difference.
what im saying is put a 16amp caravan plug on the charger (already done) and when my electrician installs a socket in my garage have him limit that socket to 15amps and 230v. as i have read that power can fluctuate to 240v + at night time which also kills jap chargers
There is no practical way for an electrician to limit an individual circuit run from your fuse (breaker) board. The load you plug in determines the current drawn and the circuit breaker limits it to a safe level for the plug and the wiring by disconnecting at its rated load (6A, 10A, 15A, 20A circuit breakers are common). You are right that the supply voltage varies, you might even see as much as 250V on occasion which will give that Japanese voltage rated transformer a fright. Once again there is no practical solution an electrician can use to limit the voltage at an individual outlet. Sorry.
