PL1220 Owner’s Manual
15
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-
conductor receptacles that accept the machine’s plug, as shown in Fig. 1-1. Repair or replace
damaged or worn cord immediately.
1.7.2.2 Grounded, cord-connected machines intended for use on a supply circuit having a
nominal rating less than 150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated
in Figure 1-1, the machine will have a grounding plug that looks like the plug illustrated in Figure
1-1. A temporary adapter, which looks like the adapter illustrated in Figure 1-2, may be used to
connect this plug to a matching 2-conductor receptacle as shown in Figure 1-2 if a properly
grounded outlet is not available. The temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and
the like, extending from the adapter is used, it must be held in a place with a metal screw.
In Canada, the use of a temporary adapter is NOT permitted
by the Canadian Electric Code.
1.7.3 Extension Cords
DANGER
Use proper extension cords. Verify the extension cord is in
good condition and is a 3-wire extension cord which has a 3-
prong grounding type plug and matching receptacle which will
accept the machine’s plug.
When using an extension cord, be sure to use one heavy
enough to carry the current of the machine. An undersized
cord will cause a drop in line voltage, resulting in loss of
power and overheating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the cord.
The tables below show the correct gauge to use depending on the cord length. If in doubt, use
the next heavier gauge. The smaller the gauge number, the heavier the cord.
