"Gentleman who owns Solarize was professional and courteous. He communicated well with the manufacturer and convinced them that a replacement inverter was needed based on the data he saw and the manufacturer had seen. It's what we were hoping for."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

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

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

Both can and canless lights have distinct advantages, and the better option depends on your specific needs and preferences. Canless lights are often preferred for modern homes due to their slim, low-profile design, energy efficiency, and ability to fit in tight spaces with less ceiling depth required. Can lights, or traditional recessed lights, provide a classic look and may be better for high ceilings or areas that need stronger, more focused light. While they can be durable, they typically require more ceiling space and installation work. Ultimately, you should choose canless lights for a modern look and energy savings, or opt for can lights for a traditional aesthetic and robust lighting in larger spaces.

If you have a garage heater that is 1,500 watts or more, it will need its own breaker. As a good rule of thumb, no appliance should exceed 1,500 watts per outlet for best outcomes. Consult a local garage heating service to determine the power needs for your outdoor or indoor space.
