I suppose the term can mean many things to different people. What part of
the wiring was being referred to by the term? If it was the circuit breaker
panel, there are "piggyback" breakers, which are essentially two circuit
breakers that fit in the space of a standard single breaker. It's also
possible that the term is being used for an Edison circuit, or multiwire
branch circuit, which is two hot legs of different potential, that share a
neutral conductor. Both are standard wiring methods, and when done properly
work fine

What does it mean when the (electrical) wiring in a house is
piggybacked? Is that good or bad (is it a cheap way of doing things)?
Is there any complications that could happen because of it?
