Ganged Extension Cord


OK, so this may sound like a silly question, but let me explain the context.

I DJ Part time and some times use lights on poles. I average three lights per pole, each with its own power cord. What this means is that I have to have three extension cords run to each pole. (total of 6)

My questions is does anyone know of an extention cords that have multiple receptacles at one end, and corresponding plugs on the other end, but are run as a gang? right now, the only thing I can think of is to run three cords together and tape them together so I can do one run.

I know that cords ganged together can generate heat, however the load per light is negligible. The only problem is that each light has to be controlled individually

There are extension cords made with triple tap end and triple tap adapters. These seem to be commonly available.

You can't just run one cord and use a splitter?

There are cords available(like Ridgid from HD) that have 3 receps on the end.

Or are you needing 3 male cord ends and 3 female cord ends to feed each pole?

The way I understand the OP's situation is to have 3 separate runs, I am assuming this is being run to a switch panel. I understand what it is you are trying to do and I am pretty sure there is nothing like you want pre-manufactured. Honestly I don't think there is really any "easy" option other than to just tie the cords together. Personally i'd prefer zip ties over tape, since over time tape can become sticky (yes even gaffers tape). I just ended up buying some DMX controlled dimmers and a USB controller for my laptop, now I can control 2400 watts at each dimmer with 4 channels, and put them where ever I want, with an XLR control line and a single power cord to each dimmer.

If there are 3 lights per pole, each individually controlled, you could make your own system using 5 wire cord. 3 wires would control the lights, one for a neutral, and one for a ground.

5 wire cord might be hard to get for a DIYer, if you go this route make sure the cord is rated at least 300 volts, don't use thermostat wire or anything like that.

4 conductor cable wouldn't be hard to come by, especially in a rubber jacket type. I've seen some eBay sellers with 4 conductor 13guage wire, though depending on how much power the lights use (when I think DJ and how these are switched on and off, I am thinking these must be around 2-300 watts a piece) and that can really add up on that neutral wire. Though consider that 14 gauge is used in 15 amp circuits at 1800 watts, 13 gauge ought to be able to handle the 600-900 watts that 3 lights would use. But again this would only be a 4 conductor cable. The 5 wire cable would be ideal, but good luck finding it in a cable style rubber jacket. Although just thinking about it, there must be a supplier out there since Neutrik makes the wonderful 8 pin speakon connectors so there must be a supplier with 8 wire cable. Though it won't be cheap. Here is a link to a 25' 8 pin speakon cable: http://cgi.ebay.com/Neutrik-Speakon-...QQcmdZViewItem

50 bucks for a 25' section of 8 conductor 16 gauge!

Do not use common neutral in this kind of cable. If somebody have swapped the live and neutral somewhere upstream or an upstream neutral wire failed and is disconnected then an unplugged plug's pins become live and you may electrocute

Common ground is ok

The following types of cable can be usefull :



5 wire cable for 3L appliances (2 lights)

Split air conditioner cable to connect the units : it may have up to 8 conductors of mixed 1.5 and 2.5 mm^2 which is 10 and 16 A respectively (3 lights)

Those you can get from people dealing with air conditioning



Control systems cable (some have 12+ wires = 5+ lights) I saw such things in industrial machine setups and in standard house lifts (it is used to connect the floors panel)

Try people dealing with industrial electricity or lifts



You can buy everything online



For the ends of the cable : group the appropriate wires together

Include the single earth conductor in one of the groups

Add a wire from this group back to the place where the cable splits and into another group and so on to ground all the groups

Shrink wrap each group in 1 or more coats

Shrink wrap together the place where the cable splits

can you go to a local electrical supplier? around here they do cash sales at certain hours.

You can easily get 4 conductor cabtire wire there. It's not cheap but nothing near the high price of a retail box store like HD

Check this one out. I use these on the job. Much better than hacking together some dangerous, non listed, piece of junk.

Short 1 foot cords like this are also available for less money.

Jrclen, the op wants to be able to control the lights individually, not all at once.

I think we've established that he needs seperate conductors to control each light.

Oh Yeah. I reread the OP and he wants multiple females and multiple males. I missed that second part. To me that sounds like multiple cords.

You may use zips on the cables

I dont like tape. it leaves some sticky remains where ever you use it. And it cannot be reused

Zips can be opened a number of times with a hair pin or opened by hand if initially closed in the wrong direction
