Electrical questions, answered by experts

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

In the case of electrical overflow, an ungrounded outlet should trip the circuit breaker, staving off dangerous scenarios. However, this is not always the case, especially if the wires and circuit breaker are worn down or damaged in some way. Ungrounded wires melt over time as they are introduced to more and more electricity. In other words, a circuit breaker offers protection in most instances but not always, and that’s where the danger lies with ungrounded outlets.

A 60W LED bulb is likely labeled as “60W replacement” on the package—that’s because it provides about the same light output as a 60W incandescent bulb. In reality, it likely uses less energy—usually 15 watts or less. If that’s the case, then it’s perfectly fine to put a 60W LED bulb in a 40W socket. Your best bet is to read the package carefully. It will tell you the LED bulb’s actual wattage, and as long as it’s lower than the fixture, the bulb will be safe to use.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

Most 200-amp service breakers can support 40 to 42 slots for single-pole breakers or 20 double-pole breakers. However, you should not use all of the breakers at the same time. Avoid using more than 160 amps worth of power at any given time to avoid overloading your 200-amp system.
