Q: What size wire should I use for a 30-amp hot water heater?

• <div><p>The <a href="https://www.angi.com/articles/wire-guage-amp-chart.htm">standard copper wire gauge</a> to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.</p></div>

Q: How often should a gas water heater be replaced?

Q: Does installing a water heater yourself void the warranty?

• <div><p>Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. </p></div>

Q: How heavy is a water heater?
