Hi all

I have recently wired 40 amp-capable cable directly from a heavy fuse box near my battery to the rear of the car and fitted an Arrid power socket there for my fridge, lights, etc. I tried my 330w inverter on it yesterday and "boom!" - I took out the 20 amp fuse in my fuse box as I turned it on. I know the inverter works as I have just removed it from my other car.

Given that it's a 330w jobbie, I presume that at full continuous capacity it will be drawing around 27 amps. But in this case there was no load!!!! I just plugged it in - that's all. I replaced the fuse with a 30 amp one and it did it again. I wasn't prepared to go any higher as I'd be approaching the limit of the wiring's maximum rating.....

Does anyone here know what the idle current on these things is meant to be - in approximate terms? Or, have I suddenly (literally overnight) got a bad inverter?

It used to run a 25-amp fuse in the old car and there were never any problems.

Cheers and thanks for any advice :)
