"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

The standard copper wire gauge 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.

You don’t need to be an electrician to change a light bulb. You also don’t have to be an electrician to replace a light fixture with another compatible one. But, if you are installing a light fixture for the first time, it’s worth hiring a licensed professional for the job.

While a handyperson may charge a bit less, a qualified professional can make sure everything is up to code and working exactly as it should be. This is especially true for more complicated lighting projects.

When installing an outdoor outlet, it's important to proceed with caution. Unless you have the necessary training and licensure, it's not recommended to attempt this DIY. First, choose a suitable location. Make sure that the area can accommodate the outlet without overloading the circuit. You'll also need to ensure that your project complies with building codes. Next, turn off the power to the circuit, then install and wire the outlet according to the manufacturer's instructions. Once the outlet is in place, test it. Lastly, be sure to use a cover that will protect it from moisture and other weather-related damage.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

Even if you don’t have children living in your home, The National Fire Prevention Association still recommends installing tamper-resistant outlets when you’re replacing your existing outlets. 

Not only is your home likely to change hands at some point, but you may have young children over as guests. Making the switch even if you don’t currently have children living with you at the moment will help protect any future pint-sized visitors to your home.
