Are you harboring unwanted guests in your home? Rats, mice, squirrels and even raccoons are notorious for taking up residence in people's homes without asking. In addition to being a health hazard to your family, rodents love to chew, and seem to have a particular penchant for the insulation on your electrical work, which can damage your home systems and even cause a fire. Read on for tips on how to prevent these furry pests.

Watch Out for the Telltale Signs of Rats

How do you know if you have rodents sharing your home? Try these tips to track them down:

Mice, Rats and Squirrels All Have to Go

When you do discover a rodent infiltration, you need to act right away to get rid of them before they can wreak havoc on your electrical work:

Don't Neglect to Repair the Damage

If you suspect rodents have been chewing on your electrical work, get in touch with an expert electrician immediately to assess the damage and perform any necessary repairs.

5-pin SPDT (single pole, double throw) automotive relay.

Relays are essentially two parts in one package. The first part is an inductive coil (pins 85 and 86). This coil is the “trigger” function of the relay. By applying both a positive (+) and ground (-) to the contacts, current passes through the coil. When current passes through the coil, a magnetic field is generated and moves the switch (the arrow in the diagram). This is where the second part of the relay comes into play.

The second part of the relay is the “switch.” The switch has three interface contacts—common, normally closed, and normally open. “Normally” refers to the state of the relay not being energized.

While relays can be used for virtually any task, there are some very useful, simple applications for adding LED lighting to a vehicle. Please note that this wiring only pertains to the relay—not the wires in the vehicle. Before interfacing with a wire in a vehicle, always ensure you test the wire with a digital multimeter first to confirm circuit function.

Positive Switching

Positive switching is used for applications where the “trigger” for your switch or circuit is positive. This could be an ignition, brake, or reverse light wire for example.  This could be used for applications such as off-road light bars, work lights, additional brake lights, and other exterior lighting.

Negative Switching

Negative switching is used for applications where the “trigger” for your switch or circuit is negative. Negative triggers are often found in door, hatch, and trunk triggers as well as many interior switches. This could be used for applications such as footwell lighting, truck bed lighting, under-hood lighting, and other interior lighting.

Switch Activated With Ignition Override

This is useful for applications where you want to turn your light on or off with a switch but only want the light to remain on when the car is running or key is in the “ignition” position. The main advantage to this is—even if the switch is left on—the light (or output circuit) will shut off when the key is turned off so that the battery will not be run down.

When facility managers or building owners first start the search for new replacement lighting fixtures in their facility, it can seem like a long road ahead.

From all of the read this post where we talk all about what it is. From there, you can come back to this post and continue, it will really help you keep up! Now, let’s get into when high bay lighting is practical in both broad terms and specific applications it is best used in.

In broader terms, the most appropriate time to use a high bay lighting fixture is for ceiling heights that are between 20 to 40 feet high. For heights between 15 to 20, you typically are going to go with a low bay fixture, but that’s for an entirely different post. For anything lower, you will typically be dealing with tubes and panels lights, most often found in offices, hallways, and other similar type environments.

So for commercial and industrial type environments in which the ceiling height is 20 to 40 feet tall, a high bay lighting fixture is commonly the most chosen lighting fixture to install. That is the broad definition of when high bay fixtures are going to be used at the most optimal rates.

So, what types of high bays are often used and fit the purpose perfectly. Although these applications are highly relevant, there are some we have not listed and may have missed, but these are just a few of many very practical applications that high bays work perfectly in:

Gymnasiums

Think about your school gym, or even your warehouses often have tall ceilings due to storage space requirements, this need for space vertically makes their ceilings the perfect height for high bay fixtures.

Factories

Similarly to a warehouse, factories and production facilities need proper lighting to keep things safe and consistent. With proper lighting through installation of high quality high bays (such as with LED technology), you opt-in for better safety standards and higher consistency in your production efforts.

Airplane Hangars

Large airplanes call for large ceilings in the hangars and a proper lighting system is a must for this environment. When maintenance is required, you need clear and proper light to contact one of our professionals.

If you’re considering the purchase of an electric car, good for you! You're doing your part to reduce the nation's reliance on oil and cut down on fossil fuel emissions, and you get to drive around in style to boot. But with many newer models, you’ll need to set up a charging station in your own home garage. Public charging stations are not widely available, and nothing beats the convenience of having a power source right outside your door. With an electrician's help, you can install a charging station on your property and get your car up to speed quickly. Read on for some tips on how to get started.

Expand Your Range

New, affordable electric cars (those that cost around $30,000) top out at ranges between 60 and 90 miles before they need to be recharged. That doesn't do you much good for a cross-country road trip, but it should be more than enough for the average daily commute. If you can plug it in overnight, you should be good to go the next day.

Technically speaking, the charger for an electric vehicle is found in the car itself, and the box you install to provide the electricity is called the Electric Vehicle Service Equipment (EVSE). The EVSE puts out 240-volt alternating current, and the charger in the car converts it to direct current to replenish the battery. Note that you can plug into a standard 110 volt outlet for some cars, but it will take 18 hours or more to fully charge them, making it impractical for daily use.

Pick Your Charging Spot

An EVSE can cost anywhere from $500 to $1000 or more, depending on what model you need, plus installation fees. More expensive models have higher amp ratings and can charge the car faster, generally speaking – some can get you ready to go in as little as three hours. The box needs to be placed within 15-25 feet of where you park your car so you can reach it with the charging cable.

Before you start the installation process, have an electrician evaluate the state of your wiring and circuit box – some older homes may not be able to handle charging a car without a significant electrical system upgrade. If everything checks out, the electrician can hardwire the EVSE or, alternatively, install a 240 volt outlet, similar to what you use for an electric oven or clothes dryer. The second option gives you more flexibility to move your charging station in the future, although outdoor installations usually require hardwiring.

The Code of an Electrician

To read up on the specific rules about how the EVSE needs to be installed, check out National Electrical Code Article 625 – your local building code likely has the same or similar regulations.
