"Great experience from start to finish. My wife and I needed to have 2 ceiling fans and light kits installed. The work was scheduled quickly and TFC Electrical Services was even able to do the job earlier than expected. Tom and Ralph arrived as scheduled, on time and we were given a fair price quote. They had to install electrical wiring and box in our bedroom ceiling prior to installing the fan and light. They took the time to protect our furniture and floors by covering everything with protective tarps. Additionally, the installed a fan and light kit in an adjacent staircase. The concern and respect that they showed for our home was admirable and appreciated. The installations were neat, clean and expertly completed. They completed all the work in about 3 hours. TFC Electrical Services should be a model for “ALL” other electrical contractors. Any future electrical work in my home will be offered to this company. Thank you Theresa, Tom and Ralph."

"For the past 15 years Mike from Shamrock Electric has done extensive electrical work for two homes. He is personable, reliable, knowledgeable and fastidious. Recently he returned for a smaller job and completing a delicate onyx sconce installation with the same skill and expertise. I’m always confident that the job has been done right when Mike does my electrical work. I highly recommend him. He is a pro!"

"PKJ Electrical is the most professional electrician's I have ever hired. They were on time, courteous and very knowledgeable. They replaced my breaker box. I have never before seen the wires so neat and organized as I did after he was finished with my job. I will only hire PKJ for all of my future electrical needs. Thank you again for such a wonderful experience."

"Came to my house the same day and completed the job. Mike the electrician was a nice guy and did a good job. $200 the first hour and $100 each additional hour. Changed existing ceiling fan, switches and outlets. I already had the parts, took 3+ hours, cost almost $500 with tax. Not sure if this is standard. I called them after another electrician who was supposed to come that day canceled."

Electrical questions, answered by experts

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.

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.

Using too many Christmas lights can cause your circuit board to overload which can put your tree at risk of catching fire and potentially damage your home’s electrical grid. 

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

This type of conversion is easy—you’ll just need to upgrade to the correct amperage in your wires before wiring the new outlet. However, these projects can be tricky without intermediate electrical knowledge, so consider consulting a pro before flipping any switches on your circuit breaker.
