Sine Wave Inverter Anomaly
After following this recent discussion about how to best utilize a sine wave inverter for RV use I decided to go ahead and buy the 1000 watt model mentioned in this discussion since it was on sale for...

Even though the 60V seems daunting, it is harmless. If you were to measure this voltage with an analog meter you would get about 5V, not 60V.
As it happens I still have a Heathkit analogue voltmeter I built many, many moons ago :E so thanks for that tip, I'll have to go dig it out and see what difference in readings there may be between it and my DVM.
FWIW, I did try those tests suggested by vermilye ... indeed, when I load the circuit with my wife's hair dryer (on low ~ 300 watts) that fan squealing noise almost completely disappears. However, when I tried to measure current flow between neutral and ground the Surge Guard immediately decided to not play nice and turned off ... I'll have to try this another time with the SG out of the system. Great suggestions, I really appreciate all the ideas being presented! :B
