Thoughts on accessory fuse panel diagram

Not sure if this is the right forum but I figured it's the closest. I'm planning on installing an accessory fuse/relay box to clean up some wiring on my truck. Parts I'll be installing are a 100 amp breaker, 12 fuse blue sea panel, and 40 amp relays to power accessories.

In thinking, in order to maintain flexibility on the fuse panel and either have devices ignition controlled or constant, I would piggy back some switches on an ignition powered relay which should kill accessory when truck is off, and if I wanted constant power I could use always on switches.

Is anything that jumps out as incorrect looking? Or is there an easier solution to what I'm trying to accomplish? I'm looking to avoid 2 separate panels (one ignition I one constant).

 

Looks good to me.

Like the concept of using the same panel for "dual zones" (live, always & live,ignition)

 

Looks fine.

 

Where do you plan on tapping off for ignition power? im building something similar but unsure of where to tap off from for the relay.

 

I know its probably a faux pas but I have been looking in the stock fuse panel and either using an add a fuse or pulling from a missing circuit. Haven't looked too much into it but I can always pull from the coin tray panel with an add a fuse. I just want everything to be clean. I'll report back.

 

What you're proposing sounds good but seems a little convoluted. Blue Sea makes a split fuse panel (https://www.bluesea.com/products/5032/ST_Blade_Split_Bus_Fuse_Block). You could slip the main power feed after your 100 amp breaker and run the ignition switched half through a high amp relay controlled by an ignition source. I'd just pull power for the switches activating relays from a hot fuse on the coin tray panel.

 

That crossed my mind (was actually thinking two panels, one hot and one ignition) but then I am limited on how many of each type I can wire. With this set up I have have all of one or the other.
