Uf b wire in conduit.

It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground. Type uf b cable is made for direct burial underground without the use of conduit or other piping and is also gray in color and is marked as type uf b cable to denote the difference between it and the regular type uf cable which is not suitable for direct burial outside of conduit or the proper piping material. Running wire through schedule 40 pvc conduit. Wiring buried inside rigid metal rmc or intermediate metal imc conduit must have at least 6 inches of earth cover.

Where a pvc conduit may sleeve the uf cable as it leads up out of the ground to an electrical box. For 3 way switching with a switch. Uf in conduit for short sections only if a complete conduit system then individual thwn wires are used. I would feed the uf b cable into the conduit and terminate in the panel cb.

Conduit is always convienent since you can run extra hot wires ex. Out of an underground trench that is 24 inches deep. Burying the cable 24 inches requires more digging so this method only makes sense if you have easy to dig soil or are renting a trench digger. I further plan to use uf b cable.

Uf cable should not be installed into conduit with the exception of short distances such as the following. I would then run the uf b cable along the bottom of the deck to where it would eventually be buried for about 8 ft. Uf cable can be direct buried without conduit with a minimum of 24 inches of earth cover. Wiring in pvc conduit must have at least.
