i live in washington state, where septic system seem more common then city sewer. there are a variety used here but this paticular one i have a question on is the "white water" type. it is supposed to be the newest, latest, and greatest. it uses a uv light which kills 99% of bacteria prior to being pumped out of the tank. my question is this would a gfci breaker be required on an outdoor compressor which is hardwired to a single pole switch(disconnect)? this compressor is part of the septic systems air switching. i noticed that the electrician on the house next door uses a gfci breaker on his but i do not(have passed many inspections mind you) but i am curious if the inspector is just overlooking mine. granted motors and gfci's are not a good combo but that said any thoughts?
