Does anyone run a keyed aux fuse panel?

I want to add a keyed fuse panel.

Would I have any trouble running this relay to it?

 

That looks right. I'd add a fuse/ fused distribution block between pin 87 and your device(s).

 

That one will work for sure.

I’d run a fuse at its max capacity of the relay going into pin 30 and then your fuse panel that you mention going to your loads.

I’ll be installing an Egis Automatic Charging Relay which also has low voltage cutoff, and some outputs built into it as well.

same concept, different approach.

 

Please be mindful that a fuse is not really about protecting the devices. Size the fuse by wire size (wire ampacity is often first limiting factor) to prevent it from starting a fire if overloaded. If the wire ampacity exceeds all devices demand/capability, then size a fuse by that limit.

 

correct, and good point. I often forget that many people don’t understand that wire sizing is important. It’s muscle memory for me.

BTW to the original question of a keyed fuse block, I ended up tapping the cigarette lighter wire for keyed trigger. Most things seem to be negative switched so all the cab fuse block was always hot.

 

Fused ignition source in the engine bay...Inverter (if installed) also has one at pin 2 (7.5A USCU-IG No.2)
