4F: Electrical Systems, AC
The AC electrical system is controlled at the main electrical panel. It has an AC
metering section, and an AC 110-volt section. It also has the DC sections, discussed later.
Note: The panel photographs are taken at an angle to reduce glare from
the light reflections on their high-gloss finishes.
4F1: AC Panel: Metering Section
The top portion of the power switch panel is devoted to giving the operator voltage and
current indications for both AC and DC power.
The left three meters are AC voltage and circuit
#1 and circuit #2 current; the right-hand two meters are for DC power, see below.
When connected to 50-amp shore power or when the generator is running, you will
have 110-volt power on both circuits; this is because a 50-amp connection and the generator
have a three-wire plus ground connection: Two “Hot” wires and one “Neutral” plus ground.
From either “Hot” to “Neutral” is 120-volts!
In the photo, we have readings of barely over 110-volts and almost no current.
Note: In photo, inverter switch was “Off”. It should have been “On”!
The top portion of the AC and DC Power Panel. The switch (arrow) between the meters switches the voltmeter to circuit #1 (up) or #2 (down).
