What relay type do I need to feed a 8 way blade fuse holder ? I'm guessing the bigger the better, a 60 amp changeover relay ? or will the smoke come out of the wires if I do that ?
The setup
========
Big wire coming from the battery connected to a relay, relay connected to the cig ligter wire and the other side of the relay feeding the fusebox holder ?
It all depends on what you intend to run off the fuse panel.
With the exception of just a couple of device, such as a large inverter or a compressor, most things don’t use all that much power and you can usually get away with a standard 40 amp horn relay.
On the other hand, as a 60 amp relay uses no more power than a 40, it can’t hurt to use one of them and give yourself the ability to run more gear with out having to change the relay in the future.

OK, so having started this thread thinking I was just going to run a small wire for my GPS, I'm now entertaining the possibility of a relay and 8-way fuse box "just in case" - how big are these and where's a good spot to mount it? I'm thinking on the drop down panel that covers the fusebox under the steering wheel, but are they small enough to mount there?
cheers, Andy
