Double tapped breakers are a common circuit breaker defect—but they are also one of the easiest electrical problems to correct. 

A double tapped breaker occurs when two conductors are found connected under one circuit breaker lug or when two conductors are connected at the neutral bar under one screw. The problem with a double tapped breaker is that circuit breakers aren’t designed to hold these two conductors together. While they might feel secure and seem to be working fine, these conductors could loosen up leading to arcing, overheating, and safety hazards, including fire.

A double tapped breaker can also occur if your electrical work has been done by someone without correct electrical experience. This can be bad news for your home’s safety and for future building permits!

Sometimes a circuit breaker can be designed for two conductors. In this case, there will usually be a label saying so. However, a double tapped breaker can also be a defect if the breaker isn’t designed to hold two conductors. If there is no label but there are two conductors, there may be an issue with the electrical connection requiring a repair by an experienced electrician.

There are a few ways that double tapped breakers can be corrected; these include the following:

If you have no experience working on an electrical panel, it is a good idea to have a licensed electrical contractor complete the work for you. Playing with electricity without proper experience could be dangerous to yourself and your home!

Is it only the astronomers and avid stargazers who seem to have noticed that our night sky is being swallowed up in a cloud of artificial light?

Glaring streetlights, flashy billboards, automobile headlamps, overly bright landscape and outdoor lighting…. all of these factors have had devastating consequences on our environment.

“Parking lots and gas stations, for example, are now often 10 times brighter than they were just 20 years ago and light pollution continues to grow at 6 percent every year.” Paul Bogart for The Sunday Star-Ledger, A bright idea whose time has come: Turning down city lights. March 3, 2013, P6

Not only does this wasteful illumination block our view of the stars and planets, this overabundance of nightlight disrupts circadian rhythms and negatively affects all life on earth.

“Fatal light attraction” -which is produced by excessive outdoor lighting-is deadly for migratory birds, causing over 100 million bird fatalities across the United States.–www.enlightenmentmag.com, Feb. 2015

So, what can YOU do to make your home more “Dark-Sky” friendly and stop the proliferation of profuse and destructive lighting design?

1.  Become a partner with the International Dark Sky Association.  The International Dark Sky Association (IDA) is a US-based non-profit organization devoted to preserving the natural splendor and beauty of the nighttime sky.  Membership includes all 50 states in the USA and over 70 countries worldwide.

• Contact ida@darksky.org to learn more about Dark Sky awareness and support efforts to preserve and protect the nighttime environment with good outdoor and landscape lighting plans.

2.  Check around your home at dusk and after sunset.

•Make sure outdoor light fixtures are shielded and angled downward to minimize “light trespass” beyond your property.

•Install motion sensors and automated controls on outdoor security lights so they will shut off when not in use.

3.  Talk to your neighbors.

•Educate them about Dark Sky laws and help each other to light responsibly.

4.  Upgrade your home with “Dark Sky”compliant fixtures.

• These outdoor and landscape lighting fixtures are shielded to focus light downward.

•The latest Dark Sky outdoor lighting fixtures are eco-friendly and energy-efficient.

5.  Throw a Star Party

•Enjoy a view of the nighttime sky with friends.

The latest Dark Sky outdoor and landscape lighting fixtures make it easy to get on board with the International Dark Sky movement.

Battery technology has already made our lives more portable and convenient. From the disposable alkalines you used to use to power your Walkman to the modern rechargeable batteries in your cell phone and laptop, they allow us to take our work, entertainment and communication systems on the go. But batteries might have an even grander destiny: they could revolutionize the way we generate and use energy all throughout the home. Read on for a glimpse into our battery-powered future.

From Electric Cars to Your Living Room

Leading the charge into the brave new world of batteries is Elon Musk, CEO of Tesla Motors. Musk recently launched Tesla Energy, a suite of batteries designed to facilitate flexibility for consumers and ultimately pave the way to an energy grid that doesn't rely on fossil fuels.

"Our goal," Musk said at a press conference, "is to fundamentally change the way the world uses energy."

Tesla used its expertise in designing batteries for electric cars to make batteries bigger and more powerful. The company’s new lithium-ion batteries are optimized to enable “homes, business, and utilities to store sustainable and renewable energy to manage power demand, provide backup power and increase grid resilience,” the company promises.

Energy at Any Time of Day

Because Tesla’s new battery technology allows residential and business users to store electricity until it’s needed, it creates the opportunity to purchase electricity during off-peak time, easing the stress on our electrical grid. It also helps users get more out of sustainable but intermittent fuel sources like wind and solar.

If the technology catches on, consumers can take better advantage of utility time-of-day pricing. Some utilities in North America sell electricity at cheaper rates during nights and weekends, when there is less demand. A homeowner could therefore charge a battery at night and use it during the day, which saves money for them and reduces the generation cost for the utility company by smoothing out the demand.

Furthermore, as solar and wind technologies become cheaper and more viable, the ability to store their output means that they can further cut into the market share of fossil fuels like coal and natural gas, reducing human impact on climate change.

Keep the Lights On and the TV Running

Another advantage of the enhanced storage potential is that homeowners will still have power in the event of a blackout or other disruption to the power grid. And people who want to go off the grid entirely with solar energy can do it without worrying about running out of power during the night.

The batteries are expensive, starting at $3,000 for residential models. If the program takes off, the price should fall and ever-better technologies will be developed to improve storage, capacity, transmission and other specifications.

For now, the Tesla batteries look like a useful, if expensive, addition to the energy-conscious homeowner's arsenal. If prices do continue to fall, however, the batteries could transform into something truly revolutionary.
