suffolk county, NY electric code requirement


Hello

I want to add lighting along my driveway (not low voltage) and have about a 80-100 foot run from my source. what type and gauge cable should i use for 125v 20 amp circuit? how deep does it have to be buried and does it have to be in conduit of any type?

thanks

Actually it's 24"; unless it is under a residential driveway or parking area, then it is 18"; or if it is protected by GFI before it goes underground then it is 12".

NEC T300.5 or NYS Resi Code Table E3703.1

Why not just solor lights? No digging, no wiring.

That is just reinforcing Speedy's point that in order to use the 12" for UF cable, it would need to be GFI protected.
