The ampacity of 12/2 direct burial wire, such as the Landscape Lighting 12V Direct Burial Cable, 12/2 AWG, 100 Foot Spool, is generally around 20 amps for low-voltage applications. This is in line with NEC guidelines for copper wire with standard insulation at typical ambient temperatures. However, factors like installation conditions, soil thermal properties, and the presence of conduit can impact the maximum safe current capacity. For landscape lighting, where the wire is buried, it's crucial to consider these variables. Always consult local codes and a professional electrician to ensure safe and efficient operation.
