Out building feed from house

[jp480volt]

We have an existing 60 amp single phase 3 wire UF cable from house panel.
Is it correct to drive new grounding electrodes and not bonding neutral?

Welcome to the forum!

It depends on what you are calling a "3-wire" cable. If you mean 3-wire plus ground (EGC) then yes, you need a GEC and separate neutrals/grounds. Also, the GEC has to land on the EGC bar.

If you mean 3-wires total, and if this is a new install, it's not allowed anymore. You would need the "4th" wire. In times past you could run the cable without ground (depending on circumstances such as no waterlines or other metallic paths between buildings) then bond the neutral to the cabinet along with the GEC.

assuming 240/120 and 3 wire with ground.. yes

Depends on what you mean by existing and if it's only 3 conductors. Prior to the 2008 NEC it was permitted to bond the neutral at a separate structure when that structure met a few conditions. If those conditions are met and it's prior to the adoption of the 2008 you can leave it and install a GES.

3-wire= (2-hots, 1-neutral NO EGC) wire is existing wire. Feeds well pump and lights.

This shows neutral grounded again.

The ground rod, equipment grounding conductor's and neutrals must all be bonded together in the panel at the outbuilding.

This must be some ancient UF.....~RJ~

Not necessarily. As mentioned, the code changed in 2008, and many jurisdictions lag years behind. For example NY is still on 2014.

I think Steve was referring to the UF without an EGC. I used 10/3 NM without an EGC in the late 70's early 80's for dryers.
