"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."

"Outstanding, Marty helped us troubleshoot why we lost electricity in two rooms. He was always upfront with the potential causes and gave us options to correct. This is our second time hiring Marty and definitely won't be the last. Professional, knowledgeable and reasonably priced."

"I am writing to express my sincere appreciation for the outstanding work performed by Diamond Electric during a recent electrical service upgrade at our property. From start to finish, the entire crew demonstrated professionalism, punctuality, and exceptional craftsmanship. They arrived on time, communicated clearly throughout the process, and completed the work efficiently and safely. What stood out most was their attention to detail—even the smallest aspects of the job were handled with care and precision. It’s not often that you come across contractors who combine technical expertise with such a strong commitment to quality and customer satisfaction. I would not hesitate to work with them again, and I highly recommend their services to anyone in need of electrical work."

"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, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.

If you need to visually inspect your Christmas lights to determine which are good and which need replacement, there are a few things to look for. First, look for discoloration, such as a dark spot or two on the inside of the glass. The spot is an indication of a burnt filament. Also, look for missing filaments, cracked bulb glass, and broken sockets.

You can check if an electrician is licensed in New York by using the online license verification search tool offered by the New York State Education Department. The database is updated daily and gives you the option of searching by license number, contractor name, or the name of the business.

You should never unplug or touch a buzzing outlet. If there are appliances plugged in that are causing the buzzing, wait until the appliance is turned off (or turn it off yourself) and then unplug it from the outlet. Test the outlet by plugging in something that won’t use much power—a small lamp works well. If the outlet still buzzes, have a pro investigate why.

Most 200-amp panels have 40 to 42 slots, which can accommodate 40-42 single-pole breakers or 20 double-pole breakers. Some panels can accept even more circuits through the use of tandem breakers. The exact number of breakers allowed is determined by the panel manufacturer's rating, which you can find on the panel itself. It is important to avoid using all breakers at the same time; as a general rule, you should not use more than 160 amps of power at once to prevent overloading your 200-amp system. For specific guidance, it's best to check your panel's rating or consult with a qualified electrician.
