Wiring between meter socket and main breaker panel

I suppose the wires need to be THHW since the socket and the main are both outdoor. I went to Lowes but the only individual wires they sell are THHN. Can I use a UF cable instead? I suppose the individual conductors are W grade since UF is for underground. Should I remove the cable sheath and use individual wires? Or use the whoe cable? Thanks in advance.

FYI: It is a 60A service.

Most wire I buy today lists as THHN/THWN. It usually is printed on the wires as "THHN or THWN"

Check it out.

Thanks. I will check the print on the insulation tomorrow.

No, don't use UF. The THHN at the store is probably THHN/THWN just look closely at the wire insulation.

Even though NM and UF cable are often manufactured from THHN/THWN, you can never use the individual conductors with the outer jacket of the cable removed as the conductors are not specifically labeled for that purpose. It's somewhat of a technicallity, but it's not THHN/THWN unless printed on the conductor jacket.

If it is listed as UF what would be the point of removing the jacket?
