Section 437-004-2860 - Flexible Cable and Extension Cords

(1) Extension cords used with portable electric tools and appliances must be at least three-wire type and have an approved grounding plug and receptacle providing ground continuity.

(2) Use only extension cords rated for the intended use.

(3) Do not use worn or frayed electric cords and cables.

(4) Protect flexible cables and extension cords against damage caused by traffic, sharp corners, pinching or projections.

(5) Cover or elevate cables that pass through work areas to protect them from damage.

(6) Do not use staples to fasten flexible cables and extension cords. Do not hang them from nails or suspend them by wire.

(7) Do not use flexible cables and extension cords as a substitute for fixed structural wiring.

(8) Flexible cables and extension cords must not run through holes in walls, ceilings, or floors or through doorways, windows, or similar openings, except during construction.

(9) Electrical conductors must be spliced or joined in splicing devices suitable for the use, by brazing, welding or soldering with a fusible metal or alloy.

(a) Secure soldered splices first mechanically and electrically without solder, then solder. (Use rosin-core solder, NOT acid core solder, when joining electrical conductors.)

(b) Insulation on splices and joints and the free ends of conductors must be equivalent to the original insulation.

(c) Splices for flexible cords must provide flexibility and use characteristics of the original cord. Vulcanized splices or equivalent means, such as shrinkable materials, are acceptable for repairs.
