I hear you also sell extension cords with 2 male ends! Very hard to find!

Yea, I guess you're right. The best repeat customers are the ones that don't die from using your product!Originally posted by physis:

That is, unless your target market is men who dislike their mothers-in-law, and are looking for a good birthday present.

In the UK they do have over curernt protection in the cord caps.

Re: oh my!
Well, if it makes it all better, they also sale this on their website.

Re: oh my!
In Europe, the wiring in many homes and offices is not linear like it is in the U.S. (A string of daisy-chained outlets.) They use a "ring circuit" typically rated at 40 amperes, utilizing only #12 ga. wire. They can do this because each receptacle is tied to the "ring" WITHOUT EVER CUTTING THE WIRE. The circuit "returns" to the 40a breaker.
Since electricity takes the path of least resistance, current will flow to all the connected devices from the shortest direction between the breaker and the load. If a large load (Such as a "cooker," or an air-conditioner) exceeding the capacity of one #12 is connected, current will flow from BOTH directions along the ring.
Because this system allows a lot of power to be drawn from any receptacle, each device sold with a plug has it's own built-in fuse protection within the cord cap.
This syatem eliminates all those NEMA devices we have - like 220v 15a receptacles and 120v 20a receptacles etc. Virtually anything electrical in Eurpoe uses the same cord cap. Most Euroeans have never seen the inside of their breaker box.
For a very good reason, and why many Europeans call receptacles "mains." ("Is there a mains connection anywhere around here?")

No, the current always takes all available paths.

LawnGuyLandSparky,

LawnGuyLandSparky,
this is not quite the way it is, for an accurate explanation of the UK ring circuit Click Here
As Don points out, current will divide and flow in all paths proportionate to the resistance/impedance of the available paths, this will happen with any current regardless of load size.

Re: oh my!
The wiring I found in the walls and boxes looked very much like flexible cord to me. Stranded, 16 gauge for lights and recps.
I have no idea if it was ran in a "Loop" as opposed to daisy-chain. And to me, I have Always thought that (loop) was a great idea. The load would always be "Shared" by 2 wires.
Not equally, but shared. Still sounds like a good idea to me, except twice as many homeruns at the panel!
Would this be a violation here?
Maybe looping the circuit "after" the homerun?
In other words to home run the circuit to outlet #1 then #2 then #3 then #4 then back to #1 again.
Dave
I have! Very strange fuses! I went to Germany a few years back. Of course I went prepared with digital meter and a few tools to examine their 50Hz system. I was very surprised when I realized it was not 240 volts with 2 ungrounded conductors but 240 volts with just one ungrounded conductor.

Roger, you posted before me! Cool, I'll have to check that out later, I have to go do some 60hz work right now!

Come to think of it, you can't parallel a hot conductor either.
Re: oh my!
Dave' I figured I would move my post to this page.
Do read the thread I linked to, there is very good information from Paul Coxwell who is an engineer in the UK, he was a member here on the old forum, now days I know he stays very busy at ECN.
