Low load, on a high amp circuit (Ed.)

[plugwash]

What is the breaker rating?

its on a 20amp d curve breaker

...it wouldnt be hard to swap the 32amp on the cable to a 16 for now so why would i swap to the commando on the wall to some 13amp plugs?

Just as easy.

 

[pegder]

Just as easy.

well whats your logic for having it on a 13amp plug then instead of the commando thats there?

 

[plugwash]

Just as easy.

Two things to swap rather than one.

And if the unit currently has a 32A plug, it probablly has a 4mm² flex, getting a 13A plug on that is likely to be somewhere between very difficult and impossible, whereas getting a 16A commando on is likely more doable.

it wouldnt be hard to swap the wire im more just talking logically it makes more sense to swap the commando with a 16amp than try to put a 13amp plug on it in my head atleast

from what i can tell it’s a slow charge so i really doubt it’s going to be alot manual says an amp so

A UPS, must have the amps input, to match load, plus to recharge the batteries in a reasonably time..

i know that but that is not my point i will not be drawing a 20 amp load it will be like 7 amps maybe 8 if the batterys are charging

I would expect the 1amp, to be when the batteries have fully recovered, the recharge current, will be much higher than than.

12 5ah batterys charging at more than an amp i feel would do damage to them over time. but eaton say in the docs its an amp so

You're going to have to do something, even if it's just buying and fitting a commando plug (more expensive than you might think) that can't be used anywhere else in the house. I don't see why you need a new 6.5m cable

You could have a simple fitting of a more common type

They're really not expensive or uncommon, especially at 16A, I've bought some decent ones from Onecall/CPC for the princely sum of 3-4 pounds or so.

"Much" is pushing it, the recharge times on 3K/5K UPSes tends to be long (in the region of several hours at a minimum), compared to the usual output load current it's usually negligible.

Having said that I've used normal rackmount UPSes like this in slightly grubby unheated environments at a previous job and it didn't look too well by the end of it, signs of rust on various elements and it drew in a lot of dirt and muck, they're really designed to be used in a clean indoor space.

I've known car batteries, absorb 20amps, when first put on charge, from a partial discharge. I accept that rate can decline rapidly, but nonetheless...
