looks like a more sensible system .....
ring mains are weird...tee hee

Do you not mean "wired"

Brian

no

The bloke at the end of the video said "ring mains are wierd"
even though he did mention that immediately after WW2
metals were expensive so using 220/230/240 volts allowed
for thinner cables.

do all American houses have to have an ugly great panel in
the house like that one ?

For a given size of house and a given number of mains sockets
("receptacles") and light fittings, do US houses tend to have more separate
circuits (and therefore circuit breakers) than a UK one? How about European,
Australian etc houses?

Is there a tendency for there to be fewer sockets per circuit, and hence
more circuits, if spur wiring rather than ring main wiring is used? Is the
main advantage of ring main that it allows thinner wires to be used (at the
expense of more length of cable) because there are in theory always two
routes that the current can take to any socket?

Has there ever been a move to fit US new sockets with a pressure-operated
switch that only makes the socket contacts and hence plug pins live once the
plug is pushed fully home, in lieu of the partially-insulated plug pins that
all new UK/European appliances must now have? Or is the risk of electric
shock with non-shrouded pins seen as acceptable given the lower voltage?
