The term “arc flash” is used to describe low impedance connections in an electrical system, which allows movement of unwanted electric discharge through the air from one voltage phase to another, or to ground. This leads to a rapid rise in temperature and pressure in the air between electrical conductors, causing an explosion known as an arc blast.

Arc blasts and the resulting heat can lead to fires, pressure waves and flying shrapnel that result in serious damage to life and property. These explosions typically occur without any warning, destroy electrical equipment completely and lead to severe injury or death of personnel present within the boundary of the arc flash.

What Are the Main Causes of Arc Flash?

Arc flash occurs when several electrical conductors are placed close to each other, with significant fault currents flowing through them. In this situation, ionization of the air can take place as a result of various factors – such as differences in potential – which leads to a low resistance path and allows current to flow through the air gap between conductors.

Many people assume that low voltage equipment is safe from arc flash, but arc flash hazard levels may be higher at low voltages, due to the high fault currents. Most incidents that occur in low voltage systems are caused by human error, e.g. a tool slipping while a technician works on electrical equipment.

Arc flash can also be caused due to:

Fun Fact: “Americans might not have a Columbus Day if Christopher Columbus had not been born in Italy. Out of pride for their native son, the Italian population of New York City organized the first celebration of the discovery of America on October 12, 1866.” *

Although declared a federal holiday in 1937 by President Franklin Roosevelt, Columbus Day is not celebrated in California, Nevada or Hawaii. Controversy over the “discovery” of America exists because native people inhabited the land prior to the arrival of the Europeans. **

While the “discovery” of America may be in question, there is no doubt that the European influence and influx of cultural diversity is worth illuminating. And, some of the most outstanding home lighting concepts incorporate Old World artistry with New World technology.

Love is in the air, which has gotten me to thinking about lighting. (Come to think of it, what time of year doesn’t do that?) If Valentine’s Day always gives you a hankering to pop Gone With the Wind or your favorite rom-com into the DVD player, have you ever thought about what goes into making those romantic films?

Color temperature is one of the first things to note when studying the lighting in a romantic scene. Is it orange? Bluish? White? Most often, warm colors add to an inviting, romantic atmosphere. For example, the warm light in this sunset scene in Titanic draws the audience in, unlike the cold, blue lighting later in  the movie, after things get dire.

2. Brightness (and Shadow)

You can judge the quality of light in a film scene through the hardness or softness of its shadows. Hard quality light has dark shadows with sharp edges, and often feels more raw than soft quality light. Soft lighting, often used in older films, has lighter, diffused shadows and tends to feel more sentimental. If you’ve seen Casablanca, you know what I mean.

Of course, there are always exceptions to these rules.

Cool lighting can still be quite romantic in the right setting. Like in this still from The Notebook:

And with advances in film technology, sharp shadows can also be quite romantic. Case in point, this still from the end of the 2005 version of Pride and Prejudice:
