When it comes to crime, it’s evident that there’s an appeal to darkness. Less visibility means less chance of getting caught. The 2014 National Incident-Based Reporting System (NIBRS)—an annual Uniform Crime Reporting (UCR) Program publication that’s released by the FBI—includes detailed crime data, such as time of day and type of offense. More than 18,000 law enforcement agencies participate in the UCR Program and provide data voluntarily. NIBRS’ Crimes Against Persons data shows that of the 1,093,466 incidents reported in 2014, 562,104 (51.4 percent) were between the hours of 6 p.m. and 6 a.m. Crimes Against Property data shows a lower—yet significant—39.4 percent of 3,493,904 reported incidents taking place between those same hours.

In an attempt to lessen crime and increase energy savings, many cities and businesses have started replacing traditional high-intensity discharge (HID) lights with LED bulbs, light engines, and fixtures. These actions have paid off. In 2008, Los Angeles began a project to retrofit 215,000 lights with LED lights. Since implementation of the project, color-rendering indexes (CRI) than HID fixtures. CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings. The CRI of an HID bulb can range from zero (high-pressure sodium) to about 65 (metal-halide). LED fixtures are capable of having CRIs of 75 and higher. Lights with a CRI of 80 or higher are considered to show colors most accurately and increase visibility, which is especially important for security purposes and parking lot surveillance.

Although thunderstorms are a rarity during the cooler months and you don’t have to worry about lightning causing a power surge, there are other factors that can cause an electrical surge in your home. Power surges happen all the time and are not only the result of a lightning striking nearby. You may not realize this, but your home is constantly exposed to small surges every single day. Each time your heater kicks on or your refrigerator goes into defrost, it draws additional power. Once the additional power isn’t needed, there is a bit of a surge. Your probably don’t even notice it happening, but your sensitive electrical equipment like your computer or gaming console are certainly effected. The Electric Connection has the Beverly Hills electrician you need to protect your valuable equipment from small and large power surges.

Whole-home surge protectors are an option you can choose to have installed now to prevent small or large power surges from damaging computers and other sensitive electrical equipment. An electrician will install the protector directly to the electric panel. This is an ideal option because your entire home will be protected instead of just the few items you have plugged into a power strip. It should be noted that power strips are not always enough to protect equipment from large power surges. However, when combined with a whole-home surge protector, you can rest assured your expensive computers, gaming consoles and screen TVs will all be protected.

The initial cost of the surge protector is minimal and is almost always much cheaper than the replacement cost of a single appliance. Because the surge protector will need to be installed directly in the electrical panel, you will need to call an electrician. Beverly Hills homeowners can rely on the friendly and knowledgeable staff at The Electric Connection to get the job done right.

Since electrical work isn’t for amateurs, many homeowners don’t know much about the electrical systems in their homes. With all the wiring hidden behind the walls, it may be that all you know is what you learned in your pre-sale inspection -- if you remember, that is.

When it comes to electrical infrastructure, one attribute that sets homes apart is the type of wiring in the walls. And for several decades’ worth of older homes, that type is old-fashioned knob and tube wiring.

What Is Knob and Tube?

Knob and tube wiring dates all the way back to the 1880s, but it was still in widespread use as recently as the 1950s. For most of its heyday, it was the most economical choice for wiring a new home, both in terms of installation and cost of materials. But by the 50s, mass production of modern electrical cables offered a cheaper, safer alternative.

This type of wiring consists of two wires -- a hot wire and a neutral wire -- strung within walls and above ceilings using porcelain knobs and tubes. The tubes provided a safe place to run wires through studs and joists, and the knobs supported the wires and made it easy to wrap them around corners.

The wires are protected with sheaths. In the early days, these were made of treated cloth, but electricians eventually switched to rubber. Neither material was designed to last forever.

Is it Safe?

Electrical code prohibits the use of knob and tube wiring in most new construction, and homeowners insurance companies often won’t insure homes until they’ve replaced these systems. While it’s true that it’s not the safest choice, knob and tube wiring can still be used safely, but with limitations and special precautions.

One thing knob and tube wiring still does well is release heat. Because the wires are spread out and suspended in air, there’s lots of room for electrical heat to dissipate, which is good for energy efficiency and the wiring itself. But that also means knob and tube wiring can endanger flammable materials like insulation.

To safely use this wiring in any structure, you must be certain that all wiring is clear of flammable materials and that the system is well maintained.

What About Limitations?

Another risk with knob and tube wiring is that there’s no ground wire, which increases the possibility of electrical shock. It also means you can’t use any electronics or appliances with a three-prong plug, as the third prong connects to the ground wire. This inconvenience is often what motivates homeowners to upgrade.

But even where knob and tube can be made to work, homeowners may want to expand that system to other areas of the home. This often means splicing new wiring and fixtures into the existing system, which can lead to overloaded fuses.

A dangerous mistake is to simply upgrade the fuses when this happens. This will get the juice flowing again, but the wiring can get dangerously hot, and the protective sheaths may have deteriorated over their decades of service. It’s a fire waiting to ignite.

Stay Safe

If your home still has knob and tube, it’s important to have it periodically inspected. Even if it’s deemed safe, there’s no substitute for the safety and convenience of modern wiring. And if you’re not sure what kind of wiring you have, just reach out to your local, licensed electricians for a quick inspection!
