In article <dl0i07$2t2$1 (AT) panix5 (DOT) panix.com>, Al Dykes says... This is the US. We don't have fuses in the wall power cable, which is what I think you're referring to. Oh dear...thats worrying. Do you have alot of electrical fires? |
(average 1.2KW to 1.8Kw), star configuration, rather than a high volt, high
wattage, ring and secondary fuse/current limiters are in the device rather
than the plug.

No, because U.S. mains are a fused/breakered low wattage, by comparison (average 1.2KW to 1.8Kw), star configuration, rather than a high volt, high wattage, ring and secondary fuse/current limiters are in the device rather than the plug. Aha. |

Not that I've noticed :-) (there is a fuse in a panel for each string of power outlets.) Same as here but Dave Maynard has just told me about the difference in |

system as the 1.2 to 1.8kw power capacity of the outlet is quite enough to
start fires with a defective cord/plug, although that tends to be more of a
shock hazard than fire because it's dern rare to have a 'partial short' in
a cord that wouldn't trip the 10-15 amp breaker. (much bigger fire hazard
was the copper/aluminum incompatible wiring problem back in the 70's)
On the other hand, since U.S. devices have always come with the proper
power plug/cord, and the fuse/current limiter is in the device, there's
less concern about people using oversized fuses like one might do with a
fused power plug (easier than finding a fuse the 'right' size).
The other potential heat source, loose wire connection in the plug, doesn't
exist in modern U.S. molded plugs (older equipment, say pre 1950s or so,
did have screws though).
