"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."

"Jim Benton of Country Boys Electric came out the day after my call for a bid.  He walked through our shell of a log cabin in the woods, was very thoughtful, made many great suggestions about where to put lights and plugs, described the work they would do and within a few days we has his written bid.  We liked and trusted Jim immediately and they started to work in a few days.  His workers were very professional, arrived on time, worked well with us.  They did all the wiring and then had to wait about a month for the sheetrock and painters to do their work.  We called them back and they were ready to install lights and fans and finish the job.  We were so please with their work.  They were very reliable and on time, even though they had to drive 40 miles from their shop to our place each day.We would highly recommend them to others.

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.

You can use a double-pole switch for a regular light fixture, but it's unnecessary and won’t be the most efficient choice. A single-pole switch works perfectly for standard lights. Double-pole handle high-power appliances that require both hot wires to be disconnected. Using a single-pole switch for regular lights is more cost-effective, simpler, and more common in residential settings.

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.

Labor, materials, job complexity, and urgency affect costs for switches and outlets; expect from $150 for simple sets to $600+ for significant upgrades.

Yes, Christmas lights on a timer are just as safe as any other Christmas lights are. Most fires caused by holiday lights are due to damage to the strings of lights themselves or from too many lights being plugged into one circuit.
