"Ron, our installer, was absolutely wonderful! He arrived on time, was pleasant, and efficient. Ron worked on New Year's Eve, was close to finishing his job, but could have stretched it into the next day. Rather than leaving us "in the dark," he worked until the job was completed that day. We appreciate all the hard work from Ron! We definitely recommend Reinhold for any of your electric needs!"

Electrical FAQs, answered by experts

The Occupational Safety and Home Administration (OSHA) requires an electrical panel to have a minimum of three feet (36 inches) of room from the front of the panel to the closest obstacle. In this case, the word obstacle refers to nearly everything, including walls, machines, and other fixed objects. Additionally, panels require at least 6½ feet of headroom in the area directly in front of the fixture. These requirements help ensure safe use of the panel and allow electricians plenty of room to work.

Upgrading your electrical panel is often worth the cost for safety, improved electrical performance, and potential long-term savings. A primary benefit is preventing electrical fires and other hazards from a malfunctioning panel, ensuring your household's safety. An upgraded panel also provides a steady flow of electricity, eliminating issues like flickering lights and frequently tripped breakers. It allows you to connect additional appliances without overloading the system, which is especially beneficial for older homes with 100-amp service that are prone to overheating. If you run large appliances like central air conditioning, heating systems, hot tubs, or saunas, you might consider upgrading to a 300- or 400-amp service to meet the higher electrical demand. Furthermore, an upgrade can lead to long-term savings on energy bills and potentially lower insurance costs.

The dials on an electrical meter simply represent the number of kWh you have used since it was installed. In a five-dial setup, the left-most dial represents tens of thousands of kWh, while the next dial to the right represents thousands of kWh. The following dials going to the right represent hundreds, tens, and ones.

An outlet can trip because the circuit it’s on is overloaded, meaning the devices plugged into it are drawing more power than the circuit can safely carry. Another culprit could be because a power surge from a storm or accident caused a problem with your local electrical grid or there’s a short or a fault causing power to run through the circuit in a dangerous or unplanned way.

Regular inspections, avoiding circuit overloads, and updating wiring when needed help maintain efficiency.
