Trouble Finding 220V 15amp Power Strip

I have two 220V lines with 20amp breakers and 15amp wire. My friend made a 220V 3 outlet power strip for one of them, and the other one is currently using a rather old grey normal power strip. Not sure how, but its been working fine, but hasnt had a lot of load to it yet. Id like to replace it and having a hard time finding one that can do 15amps / 3000W (only going to go a max of 3K watts to have some headroom on the 15amp wire).

Thats the closest thing I can find and its 2500W.

That one is 13amps with a European plug.


I would only need 4 outlets, but 6+ would be nice.

Current rating is more important than voltage rating. Even if kt doesn't specifically say 240V, it's usually rated for that.

I think all power supply cables are rated 250V for example. So are rated for 300 V or even 380V.
 
First thing you need to do before anything else is change out the 20amp breaker to match the wiring ratIng. If for some reason, you end up with >15 amps on the circuit, but less <20 amps, you could end up with a fire.


As for finding a power strip designed for 240v in North America, that isn't going to easy as most 240v circuits are intended for use by a single device (stove, dryer, AC, etc). The first one you have listed is not designed for 240v, and even if it worked it wouldn't be safe.

You might have better luck looking for a PDU for a server rack, by those aren't usually cheap.
 
You might consider calling a Electrician/Competent Contractor friend to take a look. More then likely one could set you up with a breakout box/sub panel with all your power needs+ safely and maybe easily, by rewiring your available lines from the Main Box to a Sub Panel.





I've seen peoples houses burn screwing around with their home electrical system. Improper overloads on plugs/strips, breakers, low gauge copper lines/plugs, 15a/20a misconfigured or poorly calculated loads.

Be safe and get professional help if you need it, nothings worth a fire :)
 
^^^ What this guy said.

The thought of a home made 220 V power strip just screams out a call for help of some form.

The irony of the fact if you knew anything about electricity this question would never come up.
 
eBay a few pdu's and get an electrician to wire up some L6-30 outlets.

I'm surprised we don't hear about more mining fires. Loads of bad info and decision making out there.

I just got done running installing a 125A sub-panel to power my rigs. I put a 100A breaker in the one of my 200A main panels, then ran 4 gauge wires to a little 8 position sub-panel (only about $30 at Lowes). Ran the wire in 1 1/4" conduit. 50ft run.

2 240V outlets feeding a pair of 240V UPSs and a single 120V outlet feeding a 120V UPS. There is also a 3rd 240V outlet up by the sub-panel itself, that is going to feed my GPU mining rig. I don't care if it looses power since it is never writing to anything.

Custom length 14 gauge C13 - C14 cables to make it all look purdy.

Rewiring for 240V was well worth it. UPS efficiency is now 98%:

And the PSUs in the servers are running at a little over 94% efficiency (354W DC out / 376W AC in):

^ Nice work. Jealous of your electrician skills!

I'm in the process of converting to 30A 220v receptacles for my 1200W platinum PSU's. So much more headroom for 8x1080Ti rigs than trying to balance two PSUs across 2 x 110v 15A circuits
 
Pclausen... looks great nice work. Small upfront for allot of safety/ease of mind:) Glad your doing it right :)

(Edit: Can you give us a shot of it with the panel cover on opened and closed?)

Here's one with the front panel on:

Also got the GPU mining rig in the rack, being feed from the 240V outlet mounted high,

I also ran a separate 3/4" conduit to feed a pair of quad boxes to feed the amps in the rack next to the computer equipment. I got the ones with build-in surge protectors:

yeaaaaaa network and electrical porn

that there is how u do it folks. wish i lived in a house
subpanel ftw


nice work
 
Here's some more electrical porn for you guys:

30kW Kubota diesel generator with Ethernet control interface that will power everything in case of a power outtake. The UPSs will keep all servers and the network online until generator power kicks on.

Did all the work myself. Had to use the tractor to lift and hold some of the heavy stuff in place to to install:

Getting the generator into the "power room" was also a challenge:

Once the generator was in place I put down some pavers to make a patio to cover up the mess I made on the back side of the house. Turned out pretty nice I think.
