Is there, these days, some directly buriable (like the NM variety used
that can be used per code, without the necessity of running it in a buried
I lifted this from an earlier thread to simplify matters for you:
NEC table 300.5 allows for 12" burial depth for type UF cable used on
residential branch circuits rated 120V or less with GFCI protection
a maximum 20A overcurrent protection. Note 4 clarifies this.
Yes, there is. It's called Type UF (Underground Feeder), and it's readily
available at home centers and hardware stores. If the circuit is 20A at 120V,
or less, and protected by a GFCI, you can bury it as shallow as 12 inches
If any part of the cable will be above ground, you need to make sure you get
cable that's rated for exposure to sunlight, and you may also need to make
provisions for protecting it from physical damage.
