ECN Forum Forums Code Related Discussion NEC & other Code issues gfci breaker septic

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?
thanx,

I do not believe that a GFI is required. Your concerns as to motors vs. GFI's are probably not as justified as they once were; the newer (made in past year) GFI's are supposed to be re-designed to reduce such "nuisance tripping' problems.
As I understand your application, the compressor only supplies air pressure; it is the air pressure that operates switches. In that case, you already have "removed" electrical service from the 'at risk' area, and adding a GFI -while not harmful- is, in my opinion, completely unnecessary.
