Electrical questions, answered by experts

The best place to put an electrical outlet depends on your needs. A good rule of thumb is to install outlets every 6 feet in large rooms. Hallways over 10 feet long need one electrical outlet minimum. 

If you find yourself needing extra plug-ins for all of your gadgets, you may want to increase the number of electrical outlets in your room. When adding outlets, keep in mind that older homes could have outdated electrical panels. In these cases, you may need a pro to upgrade you from 100-amp to 200-amp service before increasing the power load.

It’s a great idea to replace and update outlets, especially if an outlet stops working. New outlets work well with modern appliances and devices. Over time, outlets become old and worn—they can even become damaged, cracked, and burnt if the wiring is old and outdated. Old outlets and wiring can cause smoke, sparks, flickering lights, and an electrical fire.

Single switch installs are quick DIY projects, but you should consider enlisting the help of a pro for more complicated replacements—like a smart switch or if you live in an older home with outdated wiring. Professional electricians are trained in the latest code regulations. They are also insured, licensed, and bonded.

A house with aluminum wiring doesn't always need a complete replacement but requires careful maintenance and potential safety upgrades. Aluminum wiring can pose fire risks due to its tendency to expand and contract, leading to loose connections. Safety measures include installing aluminum-compatible outlets, applying anti-oxidant paste, or using copper pigtailing at connections. Consulting a licensed electrician for an inspection and necessary updates can ensure the wiring meets current safety standards without needing a total replacement.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.
