Electrical fires kill 485 Americans every year and injure 2,305 more, according to the American Fire Administration. Sadly, many of these deaths and injuries could have been avoided with a $10 circuit breaker. Circuit breakers are devices used to cut or break a circuit when it becomes overloaded, a sign something is wrong with the electrical installation or the appliances connected to it. GE circuit breakers are the industry standard for quality, but there are other brands you can use as substitutes. However, not all circuit breakers will work properly with your electrical installation. Talk to a certified electrician before changing your circuit breaker or any other electrical safety components on your electrical installation.
Circuit Breaker Sizing
When choosing a substitute circuit breaker you must check to see if it matches the specifications of your old one. Standard circuit breakers are classified by their number of pole breakers, amperage and voltage. Other types of circuit breakers are ground fault circuit interrupters, or GFCIs, and arc-fault circuit interrupters, or AFCIs.
GE THQL1115 Through to THQL1150
GE circuit breakers with catalog numbers ranging from THQL1115 through to THQL1150 can be substituted like for like with Cutler-Hammer circuit breakers coded CL115 through to CL150, ITE Siemens circuit breakers coded Q115 through to Q150 and Square D circuit breakers coded HOM115 through to HOM150. These are single pole circuit breakers, the most common in homes.
GE THQL2115 Through to THQL2150
GE circuit breakers with catalog codes from THQL2115 through to THQL2150 can be substituted with Cutler-Hammer circuit breakers CL215 through to CL250, Square D circuit breakers HOM215 through to HOM250 and ITE Siemens circuit breakers Q215 through to Q250 of the same amperage and voltage. These are double-pole breakers, which range from 15 to 200 amps, and are used to protect large appliances such as dryers and water heaters.
