How to Avoid Overlamping

Overlamping occurs when a lamp-holder socket uses a bulb of a higher wattage than the socket was intended for. Every lamp-holder socket in your house may not be rated to handle the 100-watt incandescent light bulb. This is a code offense and a very dangerous fire hazard.

A 100-watt light bulb connected to a 75-watt lamp-holder socket can cause the socket to melt or scorch. This could expose the wires beneath. Arcing is an increased risk, making this a potential fire hazard. Arcing occurs when sparks travel through the air from one wire, and research has proven that it is one of the leading causes of electric fires.

The listing of electrical equipment is required by the United States safety standard. Listing is a method to make it easier for electrical equipment to be accepted. Most lamp holders have a specific wattage according to the fixture. This rating is based on the materials used to build the fitting and the location it will be located. These factors can result in varying levels of wattage. However, most lamp holder sockets are 75 watts.

Some sockets within your home may be listed as 40 watts and others at 25 watts. An electrician can check the sockets and confirm the maximum power for each one.

Experts agree that 75 watts or less is the safest bulb. But, it's always a good idea to check with your electrician. Modern high-efficiency lamps use less energy and are safer. It is safer to use a 60-watt lamp for older, unmarked fixtures.

You should contact an electrician if you see a lamp-holder socket that looks scorched or melted around your house. If you prefer not to seek the assistance of an electrician and instead opt for DIY repairs, make sure you have turned off the main electricity and have the right tools.
