nice. so if you have a problem with the insulation on the cable between the wall and the equipment, there is nothing but the breaker on the ring main.. hmmm. toasty. |

Well. When does the main cable fail? That have'nt happend to me yet in this lifetime.
And the main fuses are automatic. So, It's just to flick it up again when the problem is sorted. |

Why would we want to drive on the wrong side of the road?

thats the best bit about england....the fact that we are so different, that we use metric and imperial units, have our own currency and drive on the left.

Back to the topic, (well, sort of…) you guys can still get more power from your 240V/13Amp service than we can get in the states. A ‘standard’ 120Vac outlet over here is only going to give you 15 amps for a short while before the breaker trips(and who knows where you'll find the breaker-box). In most commercial settings; 20 amp outlets are common, but still very restrictive comparatively.
Then again, if you’re going commercial, you’re going to a dedicated, isolated service anyway. |

OK Disclamer: Here's how i've always understood UK power, though i'm not a spark so could be wrong and any advice taken from here should probably be double checked first. Each individual socket in your house can handle 13amps. This value was decided in the past as being the most amount of current that a normal person will need for any single socket/device, and so the sockets plastic and components are designed to handle this without melting or failing. The 13amp fuse was chosen to match this so that it would blow in a controlled way before the plug melted in a dangerous way. It is possible to do all sorts of tricks to increase the fuse like replacing it with a piece of wire or just a bigger fuse, but then you risk more than 13 amps flowing in the socket and it causing damage. Now this raises the question, how come you can have a lot of
sockets on a single 32amp ring? In
theory, if 3 of the sockets were running at the 13 amps that would be 39amps and
you would be over the limit for the wring as a whole. Edited by kevinmcdonough - 13 July 2007 at 4:05pm |

or at your local venue where u regularily use stuff... if you regularily use 13amp+ drawing amps at home and run rigs requiring 32amp supplies, u may find yourself getting shot!!

The real difference between UK and mainland seems to be that we (in Holland anyway) have no 32A. ring supply, but only 16A. That covers the danger of burning out the mains cable. It is not protected by a 13A. fuse, but by a 16A. one, the difference is small i suppose
Usually there are 3~8 circuits to power the house, there are 6 in my house, all 16Amps. The main incoming fuse in my house is 35Amps, only one phase, and in a sealed box. This is common in Holland, allthough there are houses that have 3-phase supply, and i have seen 18 circuits in a large house. Bit overkill maybe......
The few times that i have visited the UK, i saw that you usually have a double walloutlet, that mans you can use 26Amps in a simple way.
Okay, it makes wiring and spreading the load a little more difficult, but not much.

The circuits are usually divided up between rooms. Where all the outlets are in parallels.
En example could be. :Circuit 1: Kitchen :Circuit 2: Hall, bedroom 1 and bedroom 2 :Circuit 3: Livingroom :Circuit 4: Bathroom Here in Norway newer systems would have all 16A. In older systems usualy 10A in the Circuit 2 and maybe 3 and 16A in 1 and 4. But the mains would probably only be 32A anyway. If it has the size and the need then there could be double and triple 32A on the mains. There would be no problem running 32A circuits in a house, with the mind on FIRE, if the weiring was good enough. thicker cables = more power capacity. As far as i know you usually have 3-phases 400V in the streets of UK. Here you take out 230v 3 times between the different phases. Giving you (not sure of the A) 3x32Amps 230V. Then you funny guys install 13A fuses and 13A weiring??? UK=Alot of funny solutions. |

No Hansa, as i think that i have seen it, they install wires thick enough to carry 32 A. (4qmm??)This means that (in theory)you can take the full 32A. of a single outlet. These are not made for 32A. so you would melt/burn it, the max. fuse in a plug is 13A, and all plugs are supposed to be fused.
The electrical system in GB may look funny to us, but it certainly is far from stupid!
