"Scott is excellent to work with in all aspects of electrical. I am a general contractor and Moses Electric has done all my electrical for the past 12yrs. I look to no one else. From the non working outlet or switch, to service upgrades, underground work, data, fire alarm panels, low voltage, new construction, remodeling, troubleshooting, all the way to 3 phase industrial and commercial work. Scott has been along side me for all aspects of the electrical work and never skipped a beat. I have full confidence to refer Moses Electric to my own clients, friends and family. Knowing when I pass his name along it will not come back to me with a negative effect. Always happy clients every time, in addition to being clean in all aspects of presentation and workmanship. I am not biased because I am in the trades. We rely on referrals and relationships to provide our living so there is no benefit to saying what isn't true. I highly recommend Scott and Moses Electric for any of your electrical needs. He makes the process easy and seamless."

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.

For most applications, you won’t need a neutral for 240V. There are certain codes and regulations that differ between areas so just because you technically may not need one in order for the device to function properly, it may still be a local requirement. Professionals in your area know the requirements, which is just another reason to hire one instead of taking on a project that is frankly not very DIY-friendly.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Call your utility company immediately. Do not go outside, even in your own yard, and keep pets indoors. Downed power lines pose a serious electrocution hazard. They can also cause large power surges that could damage your appliances, so it’s a good idea to shut down power to your home if possible. If your breakers trip, leave them off until the utility company finishes its repair work.

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.
