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.

No, it’s extremely dangerous to cap off live electrical wires. Working with live wires puts you at serious risk of electric shock, which can cause injury or even be fatal. Whenever you need to cap off electrical wires or complete any electrical work in general, it’s essential to shut the power off at the breaker before you begin.

It’s important to ask an electrician a few questions before you commit to hiring them so you can make an informed decision as a consumer. If you’re getting estimates or considering hiring an electrician, ask them these questions:

• Are you a full-time electrician?

• Are you bonded, licensed, and insured?

• What level of experience do you have as an electrician?

• Can you please share three references?

• Do you do residential or commercial electrical work?

• What kinds of electrical work are you most familiar with?

• Will any subcontractors be performing the work?

• Are permits and inspections required?

• Who is responsible for obtaining permits and inspections?

• What is your schedule?

• Do you offer a guarantee or warranty on your work?

• Will you sign a do-not-exceed clause to keep the job within the budget?

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.
