I have seen instances where a light switch to a ceiling fixture was put
in the neutral side, nd not the hot side of the line.
I have also seen where some hams, to save money, were using 120 volt 3
prong plugs for their mobile radios. Thinking what would happen if someone
else plugged it

Good points Richard.
Not trying be a smart a$$, so please don't take this comment that way,
but what is the service worth to the community? SKYWARN, and up here in
Canada CANWARN, are valuable services that can save lives. Property can
be replaced, lives can't. Maybe there is some local,

I've seen some shotty wiring also. Scares you sometimes thinking what can
happen especially if the wire used is too small.
One note is from the Philipenes. There they use, as many other countries do,
220 VAC, but use the same 110 outlet we use here in the US. My wife is from

As recommended by Eric, I and others a relay would be simple thing to do using
the normal outlet until it failed and then automatically switch over to the RED
outlet.

This is true. We all have the idea in us that if it is in print it is true,
more than if someone speaks the same.
Just something about it being in print especially in a newspaper or magazine.
But when you think of it all this is written by someone that puts their pants

Good idea, but batteries weigh a lot. A
Heres what we use for splitting non-redundant supplies between two separate

Or in the case of the use of a single UPS power supply, we can remove the
UPS without interrupting the feed.
Plug one feed from the live circuit, and the other from the UPS. If either

Kris,
I think you need to read the initial and follow up postings.
It is thought that if either the normally used white outlet and/or unused RED
outlet were not in use at the time of the lightning strike it would not have
tripped their breaker. So it is thought if the breaker that was to the o

Jeff,
The primary purpose of the equipment grounding conductor (green wire) is to
provide a low-impedance path for fault current on a branch circuit. The
lowest-possible impedance is realized only when the EGC is routed alongside
the phase conductor. Article 250.24(C)(1) states: "This conductor

You do have a point about the batteries. I did see that it was
