Hi guys

I am getting things together to build a big power supply for 2 chargers.

I live in a 220 Volt country and we have 15 Amp trip switches (breakers). That gives a limit of 3300 Watts. I can easily power 4 HP server power supplies from this.

I have seen guys using 2 power chords on there setups....

What the typical Amp limit for a US 110 Volt supply?

Regards
Paul

i always figured it depends on the age of the house. in place i live now and the last place i lived it was wired with a 20 amp breakers.

both places built within the last 7 years.

Who cares... its just money...

It depends on what the Nationl Electrical Code (NEC) was at the time when it was built. The Code changes about every 4 years.

Hi guys

So even if they are 20A, thats only 2200W..... not enough for 4 x HP psu's.

Thanks guys. I will have to wire 2 plugs for the occasional (maybe never....) 110V usage.

I guess you would need 2 plugs with separate breakers..... probably not in a hotel room.....

thats only when all power supply's are pulling 100%.

i run 4 dells on one plug and have not had a problem yet. they are rated 700watts each.

if i charge a 12s 5000 on one pair and 12s 3000 on the other pair as fast as the batteries will take a charge i don't trip breakers.

im guessing the dell PSU's have a very good efficiency coefficient.

Who cares... its just money...

Hey guys, I'm a licensed journeyman electrician. The typical house out let is only rated for 15 amps, HOWEVER, it is NOT supposed to exceed 12 amps for any length of time. In wattage that translates to about 1440 max. If you exceed that you risk burning up the out let and damaging your cord.

Also, Just because a plug is on a 20 amp or 15 amp breaker does NOT mean you can put that full amount on the plug. That amperage is to be dispersed between all the outlets on that circuit.

The electrical codes is NOT relevant in this discussion as it has not changed this part of the code for quite some time.

Hi guys

Thanks for the info. It is interesting how 'our 220v' houses can have about double the power......power to the people !!!!!

I thinking of making 2 separate charge cases. Would be easier to plug into different parts of the house....

Does anyone have pictures of a 'one charger in a box' setup ?

Regards
Paul

here is what i did. has two dell 700Watt units from ebay under some lexan cut out for air transfer. super duo on top running at ~24 volts.

i have two of these but the box is a modified lowes case that is fairly flimsy because of the huge weight inside so i have to use the shoulder strap since the box won't take the weight.

anyway ran a plug out of the side like on the rcgroups thread.

Who cares... its just money...

Hi TrevJones

Looks good. I has just looking at my small Futaba case. The measurements look like everything will fit nicely....
