Our electricians have been talking to homeowners in Los Angeles about installing chargers for their electric cars — that is, when their electric cars arrive. Mostly, we’ve been working out how the installations will go and setting up appointments because many homeowners are waiting for delivery. If you anticipate delivery of your electric car and want to beat the rush, now’s a good time to get your charger installed.

Nissan has delivered about 800 Leafs since December 2010, but that’s 800 for the entire U.S., not just Los Angeles. Greatly helping with that total, one ship with 600 Leafs sailed for the U.S. the day before the Japanese earthquake and tsunami struck. And then…nothing. As you know, tragically, things just weren’t the same in Japan the next day.

But recovery in Japan is moving along. Nissan has announced the good news that a shipload of electric cars (electric vehicles or “EVs“) will be landing in the U.S. today, April 27th. This is the first shipment of Leafs manufactured since the quake. Right now, demand is way outstripping supply. Over 340,000 people have registered on the Nissan Leaf website. But Nissan closed reservations for purchases of EVs at 20,000 in September 2010. They’re planning a speed-up of deliveries and will be taking new reservations starting May 1.

Of course, there are other electric cars available for middle-income families. The Chevy Volt is an electric hybrid — it can drive about 40 miles on a single charge of its battery and then turns to burning gasoline. By the end of March of this year, over 1,200 Chevy Volts had been delivered to waiting customers. Yes, Chevy has a waiting list, too, but, like Nissan, will be speeding up deliveries as the year goes on.

If you have ordered an electric vehicle and have not yet arranged for installation of an outlet in your garage for your Level 1 charger or installation of your Level 2 charger, find a licensed electrician familiar with the requirements of EV chargers.

The electrical enclosures may be one of the simplest electrical components but it is important that you design it properly. While it may be a simple component to specify, the extensive choices available in the market might overwhelm or confuse you. The most obvious choice might not always be the best in terms of reliability and long-term profitability. At the same time there may be under-rated choices that might turn out be great buys.

Let’s see how to approach enclosure design.

Critical Design Aspects to Keep in Mind

• Material Selection

Plastic or metal are the most popular choices. These groups can be further categorized into polycarbonate, ABS, aluminumpolystyrene, steel or cast iron. Select the material that can withstand the surrounding conditions of the location it will be installed in. Understand your needs and make a decision accordingly.

• Internal Design & Size of Enclosure

Consider the internal design of the enclosure. The design must meet with your requirements. Note the internal and external dimensions to make better use of the space inside, for housing your component. It is also important to take mounting options into account.

• Choosing the Right Metal

Popular choices include:

There is a very dangerous myth floating around, one which could actually result in severe injury and even death – “Electricity always follows the path of least resistance”. This is one of those myths that results from a general fact being blown way out of proportion.

Forget colleges and engineering schools, most high school students learn that electricity does behave this way, as a part of the basics of electricity and resistances. Worryingly, this myth isn’t just stated as a fact, it’s a commonly followed practice in many electrical circuit designs, especially when it comes to grounding.

Walk into any industrial plant that uses motors or pumps and you’ll find they’re all connected to ground rods. Ask anyone why that’s done and you’ll likely get the same response everywhere (even from the people in charge of the electrical maintenance) – It’s to eliminate the potential differences.

Are you thinking upping your home technology game? If you’re a movie buff, sports fan or video game expert, having a home theater system can give the experience of being in a large movie theater without having to leave your home. You can stream your favorite movie without the hassle of waiting in line for tickets or having to sit in a crowded theater. Your home theater can be as comfortable as you want for those weekends of binge watching a new TV show or playing that video game you per-ordered. Check out these three benefits of home theater systems:

If you’ve been planning a Star Wars marathon with your family or friends, having a home theater will take you to a galaxy far, far away and immerse you into the epic space battles that will make you feel like a kid again. You can drastically change your movie-watching experience from a typical hangout in the living room to a movie night experience. After a long week of work or school, your family can unwind together by selecting your favorite film and relaxing in your pajamas.

Owning a home theater system is a must for sports enthusiasts. You can invite your friends over every Sunday and watch the game on a huge screen with surround sound. Rather than watching the game on a regular TV in the living room, you could be lying in front of a high definition television that will make you feel like you are inside the stadium.

Playing your favorite video games on the big screen can enhance your game-play experience. You can journey with Link throughout Hyrule and immerse yourself in the vast expanse of landscapes that video games create. Beautiful imagery and the surround sound effects that are a part of a home theater can completely change how you play your video games. Single-player video games are all about immersion, and there is no better way to get into the game than with a high-quality home theater system.
