Q: Do you have to turn off the main breaker when using a generator?

• <div><p>As a safety measure, you should always turn off the main breaker while operating your generator&rsquo;s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.</p></div>

Q: How long can a whole house generator run?

• <div><p>As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn&rsquo;t ideal if you want to extend the life of your generator.</p><p>Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn&rsquo;t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.</p></div>

Q: Can you run a natural gas generator constantly all day?

• <div><p>Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there&rsquo;s no limit to the supply of natural gas, they don&rsquo;t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.</p></div>

Q: How does a generator transfer switch save me money?

• <div><p>It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you&rsquo;ll have to pay between <b>$400 and $2,500</b> to have the transfer switch installed, you&rsquo;ll recoup that amount later on when you don&rsquo;t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect <a href="https://www.angi.com/articles/how-to-hook-up-generator-to-house.htm">hook up of a generator to your home</a>. </p></div>

Q: What happens if my whole-house generator is too small for my AC?

• <div><p>An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home&rsquo;s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.</p></div>

Barry did an excellent job installing an outside waterproof inlet outlet that ran through a brick/cinder block wall to an electrical panel where he installed an interlock kit for my portable generator. The quality of his work was excellent and I highly recommend using B&Z Electric.
