which looks like the adapter illustrated in Figure 2(B) and (C) may be used
to connect this plug to a 2-pole receptacle as shown in Figure 2(B) if a
properly grounded outlet is not available. The temporary adapter should be
used only until a properly grounded outlet, Figure 2(A), can be installed by
a qualified electrician. The green colored rigid ear, lug or the like extending
from the adapter must be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the adapter is used, it must
be held in place by a metal screw.
Note: In Canada, the use of a temporary adapter is not permitted by the
Canadian Electric Code.
GROUNDING INSTRUCTIONS FOR 420-1902
Refer to a qualified electrician to install the proper plug on the motor cord
and to supply the proper electrical outlet.
Extension Cords
Use only a 3-wire extension cord that has a 3-blade grounding plug and a
3-slot receptacle that will accept the plug on the product. Make sure your
extension cord is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage resulting in loss of power
and overheating. The correct size to use depending on cord length and
nameplate ampere rating is No. 18 AWG, 3 conductor up to 100 feet. If in
doubt, use the next heavier gage. NOTE: The smaller the gage number, the
heavier the cord.
