Electrical questions, answered by experts

You should never plug a normal 120v appliance into a special 240v outlet, as it can quickly burn out the appliance. This will cause irreparable damage to the appliance and, in worse case scenarios, cause damage to your circuit breaker. Check your appliance’s rating before plugging it into a 220v outlet to avoid electrical disaster.

A home electrical inspection usually takes one to two hours. Full home inspections fall on the longer side, while code compliance inspections that focus on a single repair or installation may only take a few minutes. Optional add-ons like infrared inspections can add time, but these aren’t usually included in your standard inspection.

Let them know exactly what type of job you need them to do, and be as specific as possible to get the most accurate estimate. A photo of your project might help them better understand your needs. Ask what kind of prep you should complete before they visit and what kind of cleanup to expect after the visit. Finally, ask how long the project usually takes.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

The copper wire used in knob and tube wiring systems can last up to 100 years. However, it’s considered a dangerous and outdated wiring method because the cloth, fabric, or rubber insulation sheathing can become brittle and fall apart. Knob and tube wiring systems should be inspected if you’re considering buying a home with this type of wiring, or if you have problems with frequently tripping breakers, a sign that you may need to replace them.
