TT:
I agree with Phil and Tony regarding the use of exothermic welding over
clamping for underground ground (?) connections. They are maintenance-free
as compared to mechanical clamps that ought to be checked and retightened on
a regular basis. I got my OneShots from The RF Connection (www.therfc.com )
near here. If you decide to use copper flashing instead of wire, you'll
have to invest in Cadweld's commercial molds ($$). OneShots are for simple
wire-to-rod-to-wire joints.
BTW - Harger's web site is at www.harger.com . Phil mispelled the
name.

> Go to erico.com click on the Cadweld button and then select the type of
joint (wire to ground rod for example) and then one specifys the rod size
and wire size and you're left with a mold number. Then call up you local
industrial electrical supply house (not Home Depot) and place the special
order. I have to order a box of 12 minimum. Also Hargar has a similar
product called UniShots that I believe can be ordered individually. Go to
hargar.com to find their info. My cost has been about $5.50 each and are
permanent, weatherproof, and maintenance free (All you clamp guys regularly
re-tighten all your clamps as they loosen due to climatic temp changes,
don't you?). They are, pardon the pun, "The Bomb". Phil KB9CRY
