Many questions have arisen regarding therestrictions on extension chords on campus. The following guidelines should be used by faculty, staff, sudents, and vistors to assure that the extension cords in use does not violate good safety practices or fire codes. The National Electric Code (NEC) is the primary document that provides guidance in the use of extension cords. Thes guidelines are based on the NEC. If you have any questions about the NEC please feel free to contact the Safety Officer Rich Frank at x4032 or the Electrical Superintendent Doug Allison at x4706.
- Extension cords which have the UL label are approved, as long as the size and use is appropriate.
- Two and three conductor extension cords must have a minimum conductor size of 16 AWG copper.
- Extension cords are normally rated in amps, and must be used within the ampere rating. (Compare the ampere rating of the appliance with the rating of the chord.)
- Three pronged (three conductor) extension cords must be used when connecting electrical items that have three pronged plug-ins.
- Extension cords must not be run under rugs, mattresses, through doorways or windows, and must be protected from damage at all times.
- Three prong adapters are not to be used with two conductor extension cords on the female end of the cord.
- Splicing and "home repairs" of extensions cords are not permitted unless performed by Facilities Management. Insulation, strength and conductor size must not be compromised.
- Cords used in wet and/or outdoor locations should be protected by ground fault circuit interrupters.
- Extension cords with an equipment grounding conductor must be used at all times.
- Extension cords must be protected from damage, and not run through doorways or windows where the doors or windows may close, causing damage to the cord.
- Extension cords must be plugged into a circuit protected by a ground fault circuit interrupter on wet or outdoor construction and maintenance sites, or have the ground circuit checked for continuity in an assured grounding and conductor program.
- Extension cords should be a minimum of 16 AWG and be rated for the equipment in use. The following is a guide that might be helpful in selecting the cord:
