"Highly impressed with Joel and his crew. Very professional, easy to work with, reasonable, and did a great job. I ended up with an electrical emergency and Joel came right out to assess and turn off the power. Then he went out of his way to tend to that project first as well as what I had originally hired him for. I would recommend them to anyone who needs anything done. They replaced outdoor light fixtures for us, installed a flood light outdoors, installed an outdoor light, installed an outlet in our media area, cut out ancient lights from around our pool, installed new conduit and wiring for our pool equipment, installed a new pool timer, 2 new outlets by the pool, and made sure it was all safe and grounded out there. Very impressed with their service! Thanks Joel and crew!!"

"We have been very pleased to use Raynor Services for installing new outlets in our home as well as yearly service to our heating system and electrical inspection of our electrical systems. Bob E. just left after inspecting our electric and offering some options for projects we plan next spring. The attention to customer satisfaction from Raynor has been exemplary. We can always reach a live polite person by phone, receive immediate attention, and on-time respectful technicians that clean up after they are done working. Bob E. was professional and yet cheerful and friendly in explaining options and costs to me this morning. Who could ask for anything more? We do pay $19 per month to insure our HVAC and electrical systems are safe and effective. Raynor is our trusted "go-to" company."

Electrical questions, answered by experts

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.

According to the National Electrical Code (NEC), GFCI outlets should be installed in wet or damp locations where they might be splashed with water or other liquids. This is to protect against ground faults, which are more common around water. Specific areas that require GFCI outlets include kitchens (especially near counters), bathrooms, laundry rooms, basements, garages, and all outdoor receptacles. Depending on local electrical codes, you may need at least one GFCI outlet in these rooms, or every outlet in the area may need to be GFCI protected.

Yes, professional installations typically include wiring, switches, and circuit adjustments for safe operation.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

Yes, one wire is always hot on the 3-way switch, meaning it carries the electricity from the power source to the switch. If you have a 3-wire cable in your home, you have two hot wires, or line wires, coming from the power source. Typically, you’d connect the hot black wire from the power source to the traveler wire and the hot red wire from the power source to the first 3-way switch. For the second 3-way switch, you’d then connect the hot black traveler wire to the switch.
