Fuse/ Circuit Breaker to inverter

[Silver-Fox]

The box yes, but that breaker is really pants. You can’t build a effective DC breaker for that money, it needs to have a KA rating, and test accreditation. DC arc it’s dificult to extinguish, electromagnetic contacts is needed.

Ok Thankyou

I’ll look for what you suggested

Looks like I’d need a box to mount it in as well?

Like a consumer unit?

Could you use a box like this?

COMBI MEGA / MIDI Fuse Holder - 12/24V - AUTOMOTIVE/TRUCK/MARINE - 4xMIDI 1xMEGA | eBay

M5 threaded studs and hex nuts to secure 4 MIDI fuses. Robust holder with cover attached.

Yea I was going to fuse the system but I’ll go with Raul prefered method.

He knows his way around DC supplies etc

Sorry to be a pain the old cogs have been working overtime as I want to future proof.

Would there be an issue if I used a higher rated breaker for now until I up the batteries.

I’m thinking we might get a small micro wave or the popular item, coffee machine.
Along with the hair straighteners 200w and a hair dryer that seems rated around 1000w.

Please tell me if I’m thinking like an idiot

edit was thinking of a breaker rated at 125A but I’m guessing here

edit 2 I’m happy to buy a metal box with a din rail

edit 3 what size cable would you recommend

 

[Raul]

As long as the cable is big enough, for the breaker rating. You are protecting the cable.

Blimey speedy reply

I guess I can’t go too big with the breaker rating to start with?

What cable would go with 125A breaker?

Sorry to be a pain I only want to do it once and correctly

 

[Raul]

If it’s a short ish run, 35mm2 for 125A breaker.

Ok thanks.

Probably no more than 400mm to the breaker and 400mm max from breaker to inverter.

Possibly 500mm

I used a Bojack Mega fuse and box from amazon (sorry not sure how to insert a link), after reading too many reviews questioning the reliability of the circuit breakers. Comments on here also suggested that a fuse would be more reliable. I should never use enough power to cause it to go.

I think the problem with the breakers is the cheap ones.

Raul knows his stuff and the links he has supplied are for good ones.

As with most things you get what you pay for.
You don’t get a Rolls Royce for Mini money
