"When I asked him if he thought I had enough amperage to do the job of drying close, he said I did. He might be correct but I had one circuit breaker trip and I had to reset it. I suspect the new dryer is faulty and may have to be replaced (I'm having other issue with the dryer and will checked out next week,) I should have asked him how much max amps the circuit could handle. Not a born english speaker but knew what he was doing."

Electrical questions, answered by experts

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.

If your thermostat does not have a C-wire, you can hire a professional to check for an abandoned C-wire hidden in the wall, install a new C-wire, repurpose an existing G-wire to function as a C-wire, or purchase a C-wire adapter kit. 

There are some smart thermostat models that do not require a C-wire, but this will limit the functionality of the smart technology.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

An estimate for electrical work should include an estimated number and an estimated price to complete the work. An electrical estimate should also include a description of the services to be provided as well as the materials to be used, such as wiring, switches, panels, or other items, and the cost for those materials. If any tax is charged, that should appear on the estimate, too. Some estimates may include additional options that can be added to the base price of the quoted job if the customer chooses to go ahead with the add-ons.

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.
