I was presented a situation where a sump pump is required at the end of a rather long run and asked about using buck/boost transformers. My initial reaction was "no" based somewhat on previous reads here, but I could not qualify that answer.
The job consist of powering a sump pump rated 120v @ 14 amps. My first thoughts were: (a) a 2/0 AL branch circuit or (b) using standard transformers (120/480) to reduce the wire size. The electrician looking at this job is knowledgeable and had run calculations showing that the 14 amp load would lower the voltage to 111 using a #6 Cu and he asked about using a buck/boost transformer.
None of those scenarios take into account the starting load which I fear will be the main problem faced.
Any input is appreciated.
