"I was pleased with the installation of the lightning rods--communication was great and the work was done quickly. What I wasn't happy with is he quoted me a price that was less then my actual bill was BUT the price was still less then two other contractors bids."

Electrical questions, answered by experts

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.

To upgrade electrical systems in older homes, you might need to reroute new wires with lath and plaster walls. That’s because it’s more challenging to get inside the walls of an older home compared to a modern home, which usually uses drywall. But there are easier ways to level up your electrical game in an older home. For instance, you can swap out an old furnace for a new electric heat pump, or you could use a heat pump for water heating.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

It’s not a good idea to mix LED and incandescent Christmas lights if you can avoid it. LEDs and incandescents can have significantly different electrical current needs. This difference can lead to a higher risk of problems and failure for both light strands. When possible, switch all your lights over to one kind or the other for the best results. Do not connect the different types of light strings to each other, and avoid linking them to the same circuit. 

Yes, many professionals offer surge protection to safeguard equipment from power fluctuations.
