Double Insulated Tools: Tools With Two Prong Plugs
Note: The Charger included with this R/C Electronic Racing Boat has a
1.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 Outlets for
2.Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See Outlets for
Extension Cords
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 seri- ous drop in voltage, resulting in loss of power and possible tool damage.
(See Table A.)
3.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.)
4.If you are using an extension cord outdoors, make sure it is marked with the suffix
5.Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electri- cian before using it.
