It depends a lot on what accessories you want to "switch" with this panel. The switches are probably rated at 25 or 30 amps each , which is good enough for many accessories. However, for high amp draw (like cooling fans), you want to use the switch to activate a relay of an appropriate rating (you can find relays rated at 30 amps, 70 amps, etc.).
The easiest way to get power to the switches is to connect about an 8 gauge TXL wire (with 12 gauge fusible link or a maxi fuse) to your starter lug. Then run this wire up to a junction point that is near the switches. Use the hot junction point to connect power to each switch. Connect your accessory or accessory relay to the other side of each switch.
Thanks Bruce. Since all those switches are fused, is it really necessary to run relays for everything? My fuel pump only pulls ~5 amps, so I don't think a relay is needed there. My water pump pulls 11 amps, would I need a relay there? My electric fan setup would pull ~18 amps, so I can see the need for a relay there.
Of course these are all printed on their instructions, with no real numbers tested. Also, I don't know what the switches are rated at, but as long as I have a fuse, I should be safe up to the fused limit, correct? That would definitely save me some money. Thanks.
