Electrical questions, answered by experts

Aluminum wiring can pose a fire risk as it can overheat, expand, and contract, leading to failing splices and loose connections. If your home has aluminum wiring, it requires careful maintenance and potential safety upgrades. The first step is to hire a licensed electrician to conduct a thorough inspection.

A complete replacement with copper wire is the safest option but can be very expensive and is not always necessary. Other safety measures and upgrades include:

  • Copper Pigtailing: A more budget-friendly option where a short section of copper wire is added to each end of the aluminum wire. This is only appropriate for certain homes.

  • Aluminum-Compatible Outlets: Installing outlets specifically designed for use with aluminum wiring.

  • Anti-Oxidant Paste: Applying this paste to connections to prevent oxidation.

Consulting with a qualified electrician is essential to assess the condition of your wiring and determine the most appropriate updates to meet current safety standards.

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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.
