How many devices are safe per socket?

[gt74]

Guys - I've joined a company this week as an IT manager/ PBX techie. The Company is growing quickly and are installing some new servers.

I have only 4 sockets in the patch room forcing me to run 4 socket extension blocks.

I'm worried about how much power I'm drawing. Typically 600-800W power supplies on servers and a server plus associated devices per extension block.

I'm going to ask for more sockets but in the meantime is this safe?

How can I mitigate/reduce risk.

All thoughts welcome from the experts.

Many Thanks

Guy

Personally I wouldn't run a server from an extension block at all. I would have had dedicated sockets fitted for them, if you blew a fuse on one block this could potentially take out 2 or 3 servers. I assume you have some sort of redundancy power supply in them, we usually have the redundancy plugged into a different circuit as a fail safe, via a large UPS.

Hope this helps.

from what you say, each PSU takes approx. 3A so you should be OK with , say, 3 on an extn. lead, but only temp. additional socket outlets are the way forward.

If you have NOT yet blown a safety cut out, then you are probably good to go.
Just the number of devices is NOT a good indicator of load.
You have to look at load and duty cycle
Duty cycle makes a HUGE differance.

Use fused extension blocks, sorry already posted that. my bad

Do you think he should use fuses extension blocks, Pete? Just a thought....

OP, I’d definitely consider having more sockets fitted. Even on new dedicated circuits if you can.
The load seems ok on extensions, but physically you’re giving more connections that can fail, trailing leads that can be tripped over, and if there’s a problem, you can turn off one and keep all the others running.

The OP is long gone, nine years ago

 

[littlespark]

Oh wow.....
I should really check the dates.

You think he got it sorted?

9 years - that's the oldest thread I've ever seen resurrected!!

Even Mary, Joseph and the apostles would have been worried after that long
