"This project was the complete remodel of a split entry, three-bedroom house (in various states of disrepair). I was given a thorough estimate, and we reviewed the work scope in great detail. Even when confronted with some unexpected issues (items that were not obvious until we begin the demo) midstream, they gave me complete Information so that I could make an informed decision on how to proceed. Their work is excellent, they are reliable and easy to communicate with, they are proud of what they do and want you to be happy with the results. My project included general construction, electrical, plumbing, and mechanical assessment. I highly recommend Powerhouse and will continue to use them for my general contracting needs. As I recently told them, **you are my guys from now on!** Thank you, Clayton, JD, and Chris for a job well done!"

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

Smart light switches are designed to be compatible with most lights and traditional home wiring, but there are several key factors to check. First, verify your home's wiring, as some smart switches require a neutral wire to operate, which may not be present in older houses (often built before 1985). Always check the wiring requirements for the specific model you choose. Second, consider your light bulbs; while smart switches work with almost any light, using a dimming feature requires dimmable bulbs, such as dimmable LEDs. Finally, ensure you have the necessary network connection. Most smart switches need a Wi-Fi connection for remote control, but some older models might use other standards like ZigBee, which would require a compatible hub.

A multimeter does not measure frequency, charge, inductance, and other electrical quantities. Instead, it measures voltage (AC and DC), current, and resistance.

If your home already has wires for a ceiling fan (and optional light kit), then it’s quite safe to wire and install it yourself. Always be very careful to shut off the power before you begin, and confirm that the power is safely off with a non-contact voltage tester before touching anything. It’s also highly recommended to use eye protection, rubberized gloves, and tools with rubber handles to keep yourself safe from electric shock.

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.
