What Does a Transformer Warranty Cover?
Quick answer — A transformer warranty (typically 12-24 months) is a guarantee against defects in design, materials and workmanship, and covers the repair or replacement of a unit that fails under normal use. It usually excludes damage from misuse, overload, lightning, improper installation and wear. The warranty period, the defined failure and the repair/replacement terms and any payment terms should be in the contract.
