Extension Cords - Chicago Electric 92280 Assembly And Operating Instructions Manual

should electrically malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user, reducing the risk of electric shock. (see
Figure a.)
2. The grounding prong in the plug is connected through the green wire inside the cord
to the grounding system in the tool. The green wire in the cord must be the only
wire connected to the tool's grounding system and must never be attached to an
electrically "live" terminal. (see Figure a.)
3. Your tool must be plugged into an appropriate outlet, properly installed and grounded
in accordance with all codes and ordinances. The plug and outlet should look like
those in the following illustration. (see Figure a.)

Double Insulated Tools: Tools with Two Prong Plugs
4. Tools marked "double insulated" do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with the
applicable standards of Underwriters laboratories, inc., the Canadian standard
association, and the national Electrical Code. (see Figure B above.)
5. double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (see Figure B above.)
1. Grounded tools require a three wire extension cord. Double Insulated tools can use
either a two or three wire extension cord.
2. as the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a serious
drop in voltage, resulting in loss of power and possible tool damage. (see Table a.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
4. When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required. (see Table a.)
5. if you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size. (see Table
a.)
