"They contacted us in a prompt timeframe, confirmed the appt, showed up and did the job all in one day for a reasonable fee. The new fan/ light for our bathroom looks great and they cleaned up after their work. They were pleasant and wore their masks the whole time. We will definitely call Bob Daniels Electric when we have another electrical project."

"Electrical & Security Solutions are the best! I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."

Electrical questions, answered by experts

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.

Yes, wire connectors are the better option for securing splices compared to electrical tape. It is not recommended to use electrical tape as it is not secure enough to keep the splices together. Plus, electrical tape is more vulnerable to damage, which can cause a risk of fire over time. 

When converting a standard 120-volt outlet to a 240-volt outlet, the only components you can typically reuse are the existing electrical box and the hole in the wall. Everything else—including the wiring, breaker, and receptacle—should be replaced to ensure both safety and efficiency. Appliances designed for 240 volts have different plug configurations that won’t fit into a standard 120-volt outlet, making it necessary to install a compatible 240-volt receptacle. This design helps prevent overloading or underloading the power available to any one outlet or circuit.

Unless you have prior electrical experience, it’s best to hire a professional to install your new thermostat for you. Improper installation can damage wiring, lead to a blown fuse, and more.

Smart meters send the readings over a wireless wide area network (WAN) to the power company. This network allows sending small amounts of data slowly over long distances, which is perfect for smart meter readings that occur monthly. If you would prefer a smart meter, contact your power company and consider springing for the cost of replacing your electric meter.
