Will be putting in a "secondary" wired in surge protector (an Intermatic AG
2401 IND )
to try and protect a new furnace circuit board that is apparently
to lightning induced transients. It fried during last lightning storm.
Eventually, I hope to replace the electrical service box, and, when I do, I
a whole-house variety. But for now, will have to settle for the
point-of-use, wired in variety.
There is the typical on/off furnace switch located in a EMT tubing run,
about a foot or so from the furnace proper. This seems like a good place to
wire it in, and install it.
Have been thinking a bit about whether it makes more sense to wire it in on
the upstream side of the switch, or whether it should be placed on the
downstream side (the end closer to the furnace) ?
Seems to me that it probably doesn't matter at all, but thought I'd ask.
Any thoughts on ?
