Code Compliance / GFCI Services in San Antonio

At Mister Sparky^® we strictly adhere to, and comply with, the local and national electrical codes as dictated by the National Electrical Code (NEC), which is published by the U.S. National Fire Protection Association (NFPA 70). The NEC is a United States standard for the safe installation of electrical wiring and equipment. While the NEC is not itself a U.S. law, the use of NEC is commonly mandated by state or local law, as well as in many jurisdictions outside of the United States. The NEC codifies the requirements for safe electrical installations into a single, standardized source.

Some electric code violation guidelines of interest include:

Bathrooms

You can only install GFCI (ground fault current interrupter) receptacles in bathrooms.
There must be a receptacle within 3 feet of the outside edge of sink basin.
No receptacles face-up on countertops.
Because some receptacles power high-wattage devices like hair dryers, there must be at least one separate 20 amp. branch circuit.

General Rooms

There should be wall receptacles every 12 feet.
Receptacles should be on any wall space that is more than 24 inches wide.
Hallways more than 10 feet in length must have at least one receptacle.

Kitchens

All countertops receptacles must be GFCI.
There can be no receptacles more than 20 inches above countertops. (Exceptions are for the physically handicapped and for islands or peninsulas where this is not possible).
There should be receptacles above all countertops that are 12 inches or wider.
No face-up receptacles.
At least one receptacle should be located on islands or peninsulas.

My experience with The Mister Sparky team was great. I had an urgent issue with my outdoor panel following an home inspection and Timothy was on scene a couple of hours later. He took diagnostics and made sure all my questions were answered. The second day Keith and Matthew arrived and worked together to resolve issues in both our house panels. They were both professional and responsive and took their time afterwards to review their work with me.

We had an emergency situation or subpanel was going out causing the outside breaker to get up to 150 They answered my phone call and they sent Roberto out here who helped us get the stuff we need and the pricing just right and then the journeyman came and installed it all. which they also did an amazing job. Everyone quit this company was amazing and we thank you very much from the bottom of our heart

- Allen Aldrete (TRIPE)

Excellent service and installation of a severely worn out sub panel and checking our oven that caught fire recently. Timothy, Matthew and his helper (sorry forgot your name) were respectful and professional. Very clean work. Also added a surge protector to the main panel. Thank you, well worth the investment.

- Ron Heredia

I recently had Mister Sparky San Antonio replace my outside breaker panel and the sub panel located in my garage, and I couldn’t be more impressed or pleased. Matt and Keith worked together seamlessly and exceeded all my expectations. They were not only highly knowledgeable and professional, but also incredibly friendly—I felt like I had known them for years by the end of the day. What stood out most was how they handled unexpected issues in real time, taking the time to explain everything clearly so I understood exactly what was happening. They even went above and beyond their original scope of work—replacing a ceiling fan with a burned-out motor and fixing an improperly installed outdoor light from a previous contractor. It was a truly great experience from start to finish. I wouldn’t hesitate to call on them again for future electrical needs. Highly recommended!

- Darryn Christian

I needed a simple receptacle install to mount my LED mirror. Mr. Corey arrived to my house a lot earlier than expected. He was well mannered, knowledgeable, and easy going. Based on his work you could tell that it was professionally done and even cleaned up after himself. I will definitely be using this company so long as Corey works here. Thank you sir!
