I want to find an aux power source for accessories (permanent accessories) that can handle up to 20A. Is there an obvious point I could pick such up or is it just a question of looking around the fuse box area etc? It can be a permanent feed as the accessories will power up/down based on other factors.

I read somewhere that it's not advisable to take a feed straight from the battery. I don't really understand why this would be and wonder if someone could explain or clarify?

Many thanks.
 
For 20 amps I would take a feed direct from the battery to avoid overloading other circuits. Make sure that there is an appropriate fuse as close to the battery as possible.
 
Thanks Ted, my thoughts too until I read on another forum today that you shouldn't do that... although with no real explanation as to why?

Thanks,
