Last month, I posted a picture of a sectionalizer box. As promised, here is the inside. This is a nice system! One of the sets of cables coming in from the left (bottom three) is the feeder. The other set of cables (top two) go out to a new building. Two more sets of cables can come in from the right side. The three vertical bars in the center are the buss. The cables are joined to the buss with horizontal "links". The links can be removed while the buss is energized, so a cable can be disconnected, without shutting down the other cables. I don't think that procedure is practiced any longer, due to safety concerns.
Our job was to install the third cable. The cable first gets terminated in a pot head, like the two above. We stuck the cable inside the box to get a measurement.
I'm sliding the pothead body over the cable.
After filling the pothead body with compound, it's ready to be bolted into the box.
Finished product! It's shiny.
