Revisiting the Subject of Knob & Tube Wiring

March 10, 2020

Knob and Tube Wiring a Potential Hazard

Knob and tube wiring that was installed and used correctly and remains in exceptional condition is not dangerous. Nevertheless, given the fact that these wiring systems haven’t been installed in homes since the 1940’s, knob and tube wiring present in homes today are certainly aging.

Stretching and sagging is a common problem, which can lead to unsafe contact between the wires. Insulation can weaken, and breakdown to expose the copper wiring. These systems lack a grounding conductor, which are standard in today’s wiring systems to reduce risk of electrocution and electrical fires. Furthermore, when these systems were installed, most of today’s appliances didn't exist, so they were designed for much lighter electrical loads than is standard today. As a result of the increased demand, knob and tube systems are often overloaded, which cause wires to overheat and become brittle, creating hidden hazards inside the walls.

Deficient modifications are a very common problem with knob and tube wiring as well, as amateur upgrades that have often been made over the years to oblige increasing electrical needs. One common issue found in these systems is inadequately done, unsafe splices that were meant to expand the system. Fuses are another problem area, as many homeowners, in order to reduce the frequency of blown fuses, replaced properly sized fuses with ones with higher resistances. This does prevent the fuses from blowing as often, but only by allowing circuits to be overloaded, which causes heat damage to the wiring.

Home insulation and knob and tube wiring can be a dangerous combination, since this form of wiring relies upon open space to disperse heat. When insulation is placed around these wires, heat can’t escape as it should, which can cause wires to overheat or break, becoming a fire hazard. The National Electric Code (NEC) states that knob and tube wiring should not be in hollow spaces of walls, ceilings and attics that are insulated with loose, rolled or foam materials that envelope the conductors.

Home Insurance Issues

If your home has knob and tube wiring that’s still in use, you may find that home insurance companies are hesitant to sell you a policy. Some insurance companies refuse to insure homes with this type of wiring altogether, while others may insure you after your system has been inspected and declared safe by a qualified electrician.

The bottom line is that knob and tube wiring is very likely to create a safety hazard in your home. Upgrading the system is an investment, but one that will pay off in safety, peace of mind, and a more functional and efficient electrical system.

Storm Preparedness Includes a Power Generator

March 7, 2020

So far in 2016, New England and in particular the Greater Boston area was spared the high-impact weather that can come almost every season from snow storms to scorching summer heat to autumn hurricanes or more tropical storm-like conditions. Any of these natural conditions can cause power outages.

The other cause, which is too often taken for granted, are the large power utility grid outages brought about primarily by those equipment failures.

Your answer to piece of mind is a home or commercial generator: a permanently installed standby generator or an immediate back-up portable generator.

At J.P. McCurdy Electric Co., www.jpmccurdyelectric.com we offer both options through one of the world’s finest small-engine manufacturers, the Briggs & Stratton Corporation.

So here’s how to take the stress out of power interruption situations; stresses caused by a lack of refrigeration resulting in spoiled food, heating and/or cooling systems to keep you from the likes of frozen pipes or failed sump pumps and cooking stoves and ovens, all of which provide everyday living comforts.

A Briggs & Stratton Home or Commercial Stand-by Generator System installation takes care of a home’s more high-wattage appliances like air conditioning units, stoves and clothes dryers.

Depending on your business needs, type of electrical service and needs, a standby generator can provide reliable temporary power for office equipment and small machinery.

 These generator systems need to be professionally installed to your existing natural gas or propane line so when poweris interrupted, this generator automatically turns on within seconds. Now that’s worry-free piece of mind! The system also continuously monitors itself periodically so as to be ready when weather or emergency strike.

The other option offered by Briggs & Stratton is the immediate back-up power supply of the Portable Generator. This a unit growing in popularity, typically powered by gasoline and maneuverable around your property, designed to provide reliable temporary power during an outage to a few essential items like appliances, TVs, refrigerators and basic light circuits. Designed for quick transition, the home or business owner flips a switch to de-activate the everyday main panel and activate the emergency stand-by panel until neighborhood power grids are restored. Like its big brother systems, the portable generator needs to have the stand-by electrical panel to the home’s circuitry designed and installed by a professional for ensured reliability.

Again that’s where the quality work of J.P. McCurdy Electric Co. www.jpmccurdyelectric.com is your best choice.

With offices around greater Boston and the North Shore, they are certified and highly qualified electricians and technicians waiting to help your home or business be ready to deal with weather-related or other emergency conditions at a moment’s notice.
