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.

The NEC requires electrical outlets be installed in a kitchen that has a sink 12 inches wide and 24 inches deep. According to the code, that outlet must be within 2 feet of the kitchen sink. Bathrooms must have at least one electrical outlet, it must be GFCI, and it must be within 3 feet of the bathroom sink.

Unfortunately, a partial power outage without a tripped breaker often means you have a major wiring issue or that the breaker itself is going bad. When the power is out in one room but the breaker is not tripped, you need to call an electrician as soon as possible to identify the cause of the problem and repair it.

Well pumps need power to run, so they can’t function without electricity. If your power shuts off, there can sometimes be enough pressure in the water tank to allow for a lucky flush or a bit of tap water—but this won’t last long. It’s a good idea to have a backup generator or an alternative power source like solar if you’re worried about losing power.
