Re: Electrical Wire Safety (Underground)

The first comment by the first person I met in the Physics Dept. was by
one of the mechanicians ~ I was a reverse brain drain. The second;
remember we have 240 V mains, be careful.

Here any bath outlets must be powered with ground fault interrupters. I
doubt a similar safety device can be designed for lamps, so an
insulated switch is an excellent idea.

bc, whose memory is dimming.

p.s. joke: upon observing the absence of panic bars on the exit doors (A
new building,) I said they were required in the US. He answered "Being
British we don't panic."

In England where I lived (the Potteries) all the utilities are (were)
under the sidewalks covered by large paving stones set in sand. As i=

I say AMEN to that.

However, we have had a some problems in my area.
On our campus, we have had problems
that have either occurred from improper
installation and/or ground movement.

The most frequent faults have occurred where the
wires go under streets. Perhaps the road bed wasn't
