i just got the right amount of sockets and the  right wiring and trips ( i have 8 trips at 20a each (240v ) puling less than 13a per trip )

how many machines do you have connected to each strip?

would you be kind enough to provide a link to what kind of strips you have?


thanks  Smiley

just standard plug sockets wired on a ring main just like all other standard plug sockets in the uk

i just brought a load of plug sockets ( wall sockets 4 single plug sockets on each 20a trip )   i pull just over 4Amps  per plug  but only use 3 plugs on each trip ( 21 rigs at under 1kw each )



have all you guys conciderd the power factor ?

at a power factor of 1        240w at 240v would be  1Amp
at a power factor of 0.5     240w at 240v would be  2Amp                ( some older psus dont have powerfactor corection bilt in to them )

Really the best way to go about this is with a 240v circuit and a 240v pdu. You can buy a used one off amazon for about $100, most of these are rated for 30amp so that's 7200 watts. The only bad part about that is you may spend $40-50 bucks on c13-c14 cables to plug into your power supplies

This sounds a bit dangerous. With 5 riggs, you should split the load over 2 circuits. My guess is that you are drawing at least 2500W, with continuous load, that is really too much for any household power strip, not to mention that you probably stress your wall-circuit.

Is there a recommended brand or model? I'd obviously like something that can handle close to the 15 amp rating. There's a bunch of Belkins on Amazon with decent ratings but I don't know how many people are using them with this much power.

APC is usually pretty reliable.

APC is over priced crap.......
I will not  bother telling you how-many of their SHITTY rack mount APC power supplies have ruptured battery packs after a bit of use.
and because they are such a shitty design... the packs CANNOT be removed if the batteries swell a little.
The rest of the crap they sell is little better.
Seriously why buy any products from a company that cannot even design a reliable lead-acid charge circuit....

Glad to hear, would be sad if it turned into a fire. Smiley

You should check what your fuses to the wall socket is rated at. Then you can find out max load before the fuse blows. To find max power-draw, use Voltage*Ampere. Thus if the voltage is 240V and the fuse is 10 amp, max load is 2400W.

Then subtract about 20% since this will be a continuous load, and you get 2000W.

One fuse will cover several wall-outlets. (If unsure which, plug in a lamp and turn off fuses until the light goes out etc.)

Most household power-strips may get problems with 2KW after some time and heat-buildup.
I think you should rather buy some wall-plugs and some cable with 2.5mm leads. Mount them on some planks or whatever and, tighten the screws properly and make sure that they are never covered.

Since this will go on for some time, you should touch the cables every now and again. They will get a little warmer than ambient, but if they get hot you know you might have a problem, and can solve it before it's too late.

rember to acount for the power factor of the load

Yes, one should use a kill-a-watt or similar to check actual load
