adjustment on the charger is the big “Amps” knob on the front. Turn this knob up or
down depending on the amperage available from the outlet. With the “Amps” knob
in the most clockwise position a PFC-20 can draw up to 20 amps, a PFC-30 can
draw up to 30A and a PFC-40 can draw up to 40A.
EXAMPLE: A PFC-40 plugged into a standard 120V outlet at 15 amps would be
able to draw about 1,800 watts (120x15 = 1,800). The same PFC-40 plugged into a
240V outlet at 50 amps could draw up to 40A so that would be about 9,600 watts,
meaning a charge time that is over 5 times faster than in the 120V scenario.
PFC-20 Wiring
The PFC-20 is shipped with no connector on the 3-wire AC input cable. To attach
the PFC-20’s input cable to a common 110/120V three prong 5-15 or 5-20 plug run
the green (GND) wire to the ground prong, the white wire to the silver screw terminal
of one of the straight prongs and the black (line) wire to the brass screw terminal of
the other straight prong. If you want to connect your PFC-20’s input cable to a
220/240V three prong plug like a NEMA 10-30, run the green wire to the ground
prong and then the white and black wires to either of the two hot prongs.
PFC-30 Wiring
The PFC-30 is shipped with a NEMA 14-30 on the 4-wire AC input cable. Please
leave this attached and make adapter cords if you intend to change what it plugs
into. To attach the PFC-30’s input cable to a common 110/120V three prong 5-15 or
5-20 plug, purchase a 14-30 receptacle and make an adapter exactly as shown in
figure 09. If you wish to make an adapter cord to connect your PFC-30’s input cable
to a 220/240V three prong plug (like a NEMA 10-30, 10-40 or 6-50), use a 14-30
receptacle and simply disregard the white wire and the angled neutral prong. Run
the green wire to the ground prong and then the red and black wires to either of the
two hot prongs. Since there is no neutral in the older 3 prong 220/240V plugs simply
disregard the fact that your PFC charger has a 4 prong plug on it.
The PFC-30 and PFC-40 chargers come with a 4 wire AC input cable but do not
ever use the white neutral wire for anything. Even though there is a 4-wire plug on
the unit, the white wire should never be connected to anything.
PFC-40 Wiring
The PFC-40 is shipped with a NEMA 14-50 on the 4-wire AC input cable. Please
leave this attached and make adapter cords if you intend to change what it plugs in
to. The 14-50 outlet is very common for electric ovens in homes, at RV parks with
50A service and even at some public charging stations.
To attach the PFC-40’s input cable to a common 110/120V three prong 5-15 or 5-20
plug purchase a 14-50 receptacle and make an adapter exactly as shown in figure
