That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

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.

It can be safe to buy or live in a house with knob and tube (K&T) wiring, but only if the system is in good condition, functional, and has been thoroughly inspected and approved by a licensed electrician. Never purchase a home with K&T wiring without getting a professional electrical inspection first.

Key considerations include:

• Safety and Condition: An inspector will verify that the wiring is safe and has not deteriorated. Over time, the insulation can wear away, leaving exposed wires that pose a significant fire or shock hazard.

• System Capacity: The electrical service should be at least 60 amps. However, even at this capacity, K&T systems often struggle to handle the demands of modern appliances and electronics.

• Lack of Grounding: Knob and tube wiring is an ungrounded system, which is a safety concern for many modern devices.

• Ongoing Maintenance: If you live in a home with K&T wiring, it's recommended to have it inspected by an electrician every one to two years to ensure it remains in safe working order.

Ultimately, any inspection or modification of a knob and tube system should always be performed by a certified professional.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
