Any extension cord that does not meet the criteria provided here is prohibited. Acceptable cords include those that contain an in-line fuse or circuit breaker. Questions pertaining to approved types of extension cords should be directed to the Director of Residential Life. Please refer to the extension cord and power strip/surge protector usage guidelines below for more details. Multiple adapters (gang plugs) are prohibited unless such adapters have an in-line fuse or circuit breaker.
Extension Cords
1. Shall not be used to multiply the number of available room outlets.
2. Shall only be used to provide temporary power, and shall never be used in place of permanent wiring.
3. Shall be approved by a national testing agency, such as Underwriter's Laboratory (UL).
4. Shall contain an in-line fuse or circuit breaker.
5. Shall be polarized (one prong wider than the other) and no longer than six (6) foot in length.
6. Shall never be used in tandem with another cord (plugging one cord into another).
7. Shall never be run beneath carpet, rugs, or tile, areas where they may be subject to damage.
8. Shall not be used for electrical connection with heat producing or high voltage devices such as hairdryers, lamps, micro-fridge, etc.
9. Shall never be attached to building surfaces in a permanent manner (staples or nails)-this can damage the cord and present a shock or fire hazard.
Power Strips
1. Shall be approved by a national testing agency, such as Underwriter's Laboratory (UL).
2. Shall only be used to provide over-current or transient voltage surge protection for devices such as computers, printers, etc.
3. Shall not be plugged (piggybacked) into another power strip/surge protector.
4. There shall only be one power strip/surge protector plugged into a dual electrical outlet.
5. The unit shall have a built-in breaker. Such units are designed to trip the breaker if the strip is overloaded or there is a surge in electricity.
Tip: How to determine if you are overloading cords and wiring:
a. Read the appliance label to determine how many amps the appliance draws when operating. (If the label only tells you the number of watts, divide the watts by 100 to get the amps).
b. Determine the total number of amps of all appliances on the extension cord, power strip, etc.
c. Every extension cord, power strip, etc. is designed to carry a specific number of amps before it overheats and damages the wiring insulation. Read the label on each device being used. Light extension cords are usually limited to 6-8 amps. Resident room (wall) circuits are rated for 16 amps and are sometimes shared between two rooms.
d. The number of amps must be less than the capacity of the cord or circuit.
Example: A student has a 1500 watt hair dryer. This is equal to 15 amps. If plugged into a circuit rated at 15 amps, this should be safe. If plugged into an 8 amp extension cord, a hazard is created. |
