Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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 Over time, outlets become old and worn—they can even become damaged, cracked, and burnt if the wiring is old and outdated.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.

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 most common type of electrical outlet is a 3-prong outlet, which has two flat blades (one is wider than the other) and a round grounding pin. Older homes typically have 2-prong outlets that aren’t as safe as more modern options and are generally not up to current electrical codes.  Other outlets you can find in your home include 20A, 125 volt varieties for larger appliances like refrigerators or washing machines. 

There are also GFCI outlets, which protect against electrical shock in wet areas, such as bathrooms and kitchens, and arc fault circuit interrupter (AFCI) outlets, which protect against electrical fires caused by arcing.
