Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

You can certainly talk with electricians about pricing, but the pro has the first and last word on what they charge. If you feel like a quote is too expensive, you can discuss the quotes that other electricians have made and see if they’ll lower their estimate in return. Or you may be able to talk about specific parts of the estimate and how they can be changed. 

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.
