To add to this, I used 1,000vac rated ceramic caps in a VFD once some years back and they failed in spectacular fashion. This was in a 277vac system. Such caps should NOT be used on the AC line! Use

Panduit makes these type of lugs too. Some wholesale electric supply houses have them but you want the copper ones, not the aluminum kind. They are both plated and look the same, but the copper ones

Many electric company employees' are from families that have worked in the industry for several generations. If they worked in the plants they would be near hundred+ megawatt generators for decades.

"The woods" are probably the second most popular beverage location after the "unused winter farm field" :-) The only problems tend to be physical (falling branches breaking the wire, deer breaking th

The cheapest protection would be Polyethylene sprinkler pipe. Better would be rigid pvc electrical conduit. Either will be much cheaper than liquid tight pvc conduit. The sprinkler pipe would probabl

There isn't much difference in loss with the CCS center conductor. If you have very long runs and power remote equipment with power injectors then the DC resistance will likely be more of an issue. Y

Check if you can scratch some of the starter compound off of the inside of the cap from the weld metal container. I've found the older the stuff gets, the more the starter gets caked onto the cap. I'

Just to add: the spark igniter is a flint-type unit. Those used for starting a torch would probably work too but would be more difficult to aim into the mold than the gun-like cadweld ones are. -Bill

A POTS line *should* have predictable latency *during* any particular call. This is because they operate over circuit-switched networks where the connection/route is established at call initiation an

The only real difference when using reasonable-gauge sizes is in physical durability. Electrically it makes little difference since you effectively have a large number of radials in parallel so each

It's easy to homebrew something using small-signal relays. This has all sorts of added benefits (remote control, automatic switching, etc.). There have been lots of discussions on here about the corr

Don, you should request that the technician install the new conduit runs using compression couplings and connectors instead of the more common setscrew type. Compression couplings make a much better
