[TenTec] High speed washer hum/whine

[CSM(r) Gary Huber - AB9M]

Jim, I believe this one needs a bit of expansion or clarification as the code requires the green wire to be bonded (or attached ? ) at any entry or exit of any metallic conduit, panel, plate, box, or enclosure.

Something about expanding magnetic fields being choked if not done or magnetic breakers not operating properly. Its been many years since I worked on a corporate wide electrical remediation project but the green wire violation was most common after the neutral - ground bond in sub panels.

73,

Balancing both sides of the house circuit breaker box may help stabilize the fluctuations.  maybe help to keep the wine and noise on one freq more so your radio filter can work better cause of the drift.
