Electrical FAQs, answered by experts

A weatherhead, the meter base, the breaker box, and a meter panel are all vital components of a working meter riser. If one part of the system is faulty, it could damage other parts, so consider having an electrician inspect the entire unit. The cost to replace the meter panel alone may cost $500 to $1,000, so consider this in your budget for replacing the meter riser.

If the fan doesn’t have a switch, connect the white wire from the ceiling to the white wire from the fan; connect the green wire to the ground wire; connect both black wires; and connect both blue wires. If yours has a switch, the white and green wires are connected the same way. However, connect the ceiling’s red wire to the light’s black wire and the ceiling’s black wire to the fan’s black wire. 

Tankless water heaters won’t increase your electric bill. Since tankless water heaters are more efficient than tank water heaters, installing one in your home will actually allow you to save money on your electric bill. The Department of Energy estimates you can save $100 or more each year with a high-efficiency tankless water heater.

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

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.
