In days gone by, oil circuit breakers were commonplace in all electrical circuits. Today, oil circuit breakers are used less often in residential applications; however, they are still commonplace in industrial applications. If you have oil circuit breakers in your home or business or if you are an electrician who installs and repairs these types of circuit breakers, purchasing quality products and maintaining existing ones is vital to minimize costs.
Many oil circuit breakers have a rating higher than 600 volts to ensure that heavy-duty machinery can receive the power necessary without tripping the breaker. While this works for most industrial applications, other applications, such as small appliances require a smaller rating. Because it is unsafe to use a breaker with a too-high rating, you must ensure that you have the appropriate breaker for your equipment.
Periodic testing of oil circuit breakers is necessary to keep you and your business safe; however, these checks also ensure that the breakers last as long as possible. When hiring someone to maintain your breakers, be sure they check the alignment, contact surfaces and oil level. Any problems should be attended to immediately or a new breaker must be installed.
