what are the protective devices ~ $500. you mentioned?Ours is a 3cyl air cooled auto engine. although shielded, it does make noise running. It is a comforting sound for me, but Wife hates the noise. The entire deal was about $11,000 if installed during construction; unit ~ 8,000., wiring harness & controls ~$1,500., pedestal ~ 1,200, protective devices ~ $500.
