Aussiemandeus , 4 months ago Man i wish i could help, i know my wife who’s an electrician won’t reuse wires if it is a new wire job. However if you change a fan you don’t replace the whole wiring too so i think it’s more to do with cost to customers. I’m not sure about the breaker question, i work on large machines that have 24v and 400v and 230v circuits and we leave unused breakers in place. But I’m a mechanic not an electrician
