"All R responded quickly to our electrical emergency, and had us back up temporarily in less than 24 hours. They traced the issue back to our main panel which needed replacing, and scheduled that replacement by the next work day. They were professional, fast and performed quality work."

"AG Electric did a great job! First, they came and assessed my current electric panel and told me what my options were and gave me a proposal. We agreed on the work to be done and set an appointment. They showed up on time and did a great job! They left the work area clean too. I would recommend and hire again."

"Ed Riley is extremely knowledgeable about what causes lighting and how to protect from it. He explained to me which and how structures develop static electricity that lead to lighting discharges in a way that the physics made sense to me. They were also reasonably priced and kept their word. Definitely recommend them."

"Very professional. Took as much time as needed to answer questions. Very good attention to detail. Even though a few more rods were needed than originally quoted, they stuck to their original quote price. No surprises. I would highly recommend this company."

"MG Power Electric LLC did an excellent job adding a dedicated 240V line for our 220V, 3KW commercial fryer. The team was professional, punctual, and very knowledgeable. They explained each step clearly, ensured everything met code, and left the workspace clean and organized. The pricing was fair, and communication was prompt throughout the project. I would definitely hire them again and recommend them to anyone needing reliable electrical work in Brownsville."

Electrical questions, answered by experts

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.

No, not all thermostats require a C-wire. Older manual and programmable thermostats typically do not need one. While many smart thermostats do require a C-wire to function correctly, some models can operate without one, often at the expense of certain features. A C-wire provides a constant source of power, which enables the thermostat to stay connected to Wi-Fi and keep its display screen lit on-demand. If you are upgrading from an older thermostat to a smart model that requires a C-wire, you may need to install one first for it to work as intended.

Upgrading your electrical system can save you money on your monthly utility bills by powering your home more efficiently. Electrification nonprofit Rewiring America estimates that a household could save $1,800 per year on energy bills by upgrading to a modern electric heat pump, switching to a heat pump for their water, installing solar panels on the roof, and converting to an electric vehicle.

If you’re wondering whether an electrical panel in the bathroom needs to be moved, the answer is yes. Due to the risks of shocks and electrical fires, electrical panels cannot be located in bathrooms per National Electric Code Volume 70. Additionally, gasses, vapors, liquids, and temperature fluctuations can all compromise the functionality of your electrical panel, so it’s important to install it in a dry, cool, safe, and easily accessible location.

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.
