Our take on the 10/3 UF-B Solid Copper Underground Feeder Cable Gray 600V

This is 10-gauge, 3-conductor UF-B cable with solid copper conductors, rated 600V and made for direct burial. It carries a 30-amp allowable ampacity both buried and in duct, so it suits feeder runs to outbuildings, pumps and subpanels. UF-B is the standard choice where NM-B cable cannot go: wet locations, underground and outdoor conduit. The solid copper and gray sunlight-resistant jacket are the usual build for this class; the trade-off against stranded cable is stiffer pulls through conduit.

Questions and answers

What is 10/3 UF-B cable used for?
It is underground feeder cable for buried and wet-location circuits, such as runs to outbuildings, pumps and subpanels. It can go directly in the ground or in duct.
How many amps can 10/3 UF-B carry?
The allowable ampacity is 30 amps, both for direct burial and in duct. Confirm the final breaker size against your local code and the load.
Does it need conduit underground?
No. UF-B is rated for direct burial, so conduit is not required for the buried portion. Conduit is still used where the cable rises above grade or where code requires protection.
What is the difference between UF-B and NM-B?
UF-B is built for wet and underground locations; NM-B is for dry, indoor wiring only. UF-B has a tougher jacket and solid conductors that are stiffer to pull.

A single length of 10/3 UF-B cable with three conductors plus ground, in the length you select. Terminations and connectors are not included.
