UPS Input requirement...

[mrbios]

Can anyone tell me if one of these: Buy APC Smart-UPS XL 3000VA RM 3U 230V - Technical Specifications and Information | APC requires a 16amp input or if a 13amp plug will do?

 

I've got a 5000VA on a 32amp feed, and two 3000VAs on 16amp feeds, but I'm not sure if the 16a is actually necessary on the 3000 or not.

In the specifications it says that BS1363A can be used for the input. We have one of these and have used a standard 13a plug > C19 lead to connect it. Buy Power Cord, C19 to BS1363A (UK), 2.4m - Technical Specifications and Information | APC

Good stuff, i've got one of those, just wasn't sure about the amp requirements Cheers

I'm not an electrical engineer, but my KS4 Physics suggests that if you were to use a 13A circuit, while using the full 2700W and you suffered a supply voltage drop to near or below 200V then you probably blow the fuse.

 

I've periodically had supply issues where <200V was being provided, however the power draw was low enough that we've never blown a fuse.

 

That said, I made the observation to the premisis team and they put in 16A circuits for me pretty soon afterwards.

Going to get a quote from our leccy to put another 16amp line in, I'm pretty sure we had two chopped off when we had a wall removed, so chances are the fuse box still has the required components in and it's just a case of refitting the socket on the wall
