Double wall Insulated Wire, UV- Stabilized MDPE, Class 3 galvanized 12.5 gauge wire
Burying insulated wire at gate is often better than running wire overhead or using removable electric gate wire. The use of household electrical wire is not recommended for use with fence chargers due to low voltage ratings. The 12.5 gauge wire lasts longer and conducts better than 16 gauge.
It is HIGHLY recommended to run underground wire through a conduit.
