VOLTAGE CHECKS
Set voltmeter to AC Volts. Voltages should check out as follows:
Line 1 Black to Line 2 Red – 240VAC (Range of acceptability: 216VAC
– 246VAC)
Either Line to Neutral – 120VAC (Range of acceptability: 108VAC –
132VAC)
Either Line to Ground – 120VAC (Range of acceptability: 108VAC –
132VAC)
Neutral to Ground – 0 Volts
These readings should be consistent at all points in all electrical en-
closures and breaker boxes. If the readings are not in the acceptable
ranges, do not power up the system and call an electrician to evaluate
the installation.
