Waterproof Fuse and Relay Boxes - RFRM (10 relay) & RTMR (5 Relay) no Blue Sea/ SPOD

I like it lol... Next will be a custom logo/emblem

 

That's what I thought so is this individual running high amperage off fused switches only? I'm confused because I thought anything above ~10amps needed a relay, in the photo there are items at 30 amps in the fuse only slots.

I'd like the 10 but if I can get away with the 5 it will be easier to fit under the hood of my JKU (I know), so what can this box and contura switches handle without relays?

 

The switches are rated for 20amps I believe.

 

The switches are 20amp.

Of note as well, each fuse slot is rated for max 30a and the entire bus is rated for 80a (i THINK. quick google matched what i thought but it oculd be 100amp....either way its not a huge load). Which shouldnt be a big issue unless you are running tons of stuff at once or something like a big 54" lightbar (rigid's 54" can draw 29amps)

 

I just went out to the garage and tested a few of my accessories, china 50" light bar only drew 7.8 amps, my china cube lights came in at 2.5 and my front locker was 3.2. These numbers seem really low, but make me think maybe I can get away with the 5 relay unit.

Can someone verify that I tested these circuits correctly. Multimeter on 20amp setting, remove fuse, plug ends into fuse port and activate switch. Reading is amperage draw correct?

Thanks for all the help guys!

 

In line with the load, correct.

 

Sounds like you did it right. You have to remember to find amps it is Watts divided by power. So a 24 watt accessory on a a 12v system should draw approx. 2amps.

If I remember right that is.

Same with there can be a higher initial power draw. So it might be 2a to run those lights but might be a "surge" of 3.5a when you flip the switch.

 

Wattage is 'power', P=IV where I is the amperage drawn and V is the voltage. In other words, amperage is wattage (power) divided by voltage.

It's also good remember that voltage can vary between 12-14.4V depending on whether the alternator is running and what the load on the battery is. Rigid, for example, rates all their lights at 13.8V.

Also, LEDs don't really have much inrush current. That's something you'll see with HID ballasts and things with large capacitors.

 

Hi Mike,

Sent a PM just a few minutes ago about my order. Please have a look when you get a chance.

Thanks,

Are these supposed to come with power and ground leads?

 

Yes they do come with leads

 

Hmm... Mine didn't. Oh well, not worth waiting 6 months to get them delivered. I'll just make my own.

 

Are you referring to the box or switchbacks?

 

The box

 

You can see the power and negative wires marked. Yours don't have those?

 

No. Or else I wouldn't have said they weren't there.

 

Ok man. I'm just asking.

 

Sorry this whole experience with this product has been a cluster fuck. I'm just ready to have it wires up and be done with it.

 

I can understand the frustration. All you need is 6-8ga wire and rings

 

Hey guys, I was one of the original skybox buyers.

Take your time and ask questions because I think wiring this up (once you get it) requires some patience and understanding of the box itself. Otherwise things can get real messy.
No question is stupid or redundant.

Good luck!
