1.12 Junction Boxes
Weatherproof electrical junction boxes with a gasket-equipped cover are required at the end of each probe and
conduit run at the UST manhole or monitoring well location.
Wires coming off of a probe or sensor connect to prepared Belden or Alpha cable, and then go through NPT
busing into the weatherproof junction box. Bushings must be used in all junction boxes. The cable is then
routed out of the junction box via rigid steel conduit.
