We recommend installing transformers outside on a transformer stand (constructed according to our guidelines). This eliminates running wires through walls and also allows for the best dissipation of heat generated by the transformer. However, CAST transformers are UL approved for inside installation. In this case, the installer needs to follow National Electrical Code (NEC) guidelines for running wires within a structure; and must use a properly rated metal conduit when running wires through exterior walls.
