Found this on my computer, might be from the net someplace.... Possibly a 3 pole disco switching the hot leg from all 3 meters?

Three wires from pole, three meters, three phase disconnect, black & white feeders to each group of outlets, each outlet fed with two green wires.

Any guess to what voltage is delivered to each outlet?

Is this a permanent "Temporary" power distribution set up for a holiday light festival?

I hope there are fuses in that disconnect.

Why are the scorch marks on only a couple of the receptacles?

An irreverent observation here:

See the bushes behind the board? Someone spends a lot of time, and money, making their shrubs 'just right.'

Just like the housewife who agonizes over 'just the right' cabinets for the kitchen.

How is it that our work gets put in the 'leftover' pile?


Now, it's always easy to laugh at the other guy. On this board are a LOT of receptacles. How would you make such a board? (Fair warning: I had to do this once laugh )

Define the application and environment. How often used? Who is going to connect / disconnect? What are the expected loads? Who will have access to the finished assembly? where will it be installed?(geographical region)

Umm,
For a start, I'd be thinking about putting them rececpts in some sort of an enclosure or two, more than likely a weather-proof one, with a top-hinged lid so that the sockets can still be used with the cover in place.

Secondly, there'd be some sort of point of attachment below the enclosures so that any flexes that were connected to the sockets could be supported, meaning that the sockets weren't carrying the wieght of the cord.

Thirdly, all the wiring from the disconnect to the enclosures, would be in conduit.

Just a question though,
Is there really a need for 60 (30 x 2) repectacles, all in one place?
This is just asking for a tripping hazard! crazy

Mike, those are some good points.

Perhaps a piece of strut would serve as a tie-off for the cords, and help protect the plugs from strain should someone trip on a cord. Something like this:

Just wrap the cord around the strup on its' way to the outlet.


As for the receptacles themselves, perhaps this wpould be a better solution:

John,
Anything that takes the wieght off of the contacts of the socket and the pins of the plug has to be good.

I've lost count of the times I've seen pictures on the Net where there is a plug in a socket that is just hanging out of the socket at some weird angle (and people wonder how fires start?).

One other thing I neglected to remember in my post above, if this is going to be installed in an outdoors location, GFCI protection probably wouldn't be a silly idea either.
