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:

Crowds are packing amusements parks this summer as they look to let out their inner adrenaline junkie. With more than 400 amusement parks and 786 roller coasters in the U.S., there are plenty of rides to choose from. Mr. Electric® presents our favorite list of the top five roller coasters with gut-wrenching drops, jaw-dropping loops and stomach turning speeds that are sure to give surge to your summer.

This menacing roller coaster in Jackson, New Jersey at Six Flags Great Adventure, is not only the world’s tallest roller coaster, but also the world’s second fastest. Riders are launched at 128 miles per hour and reach a height of 456 feet before plunging back down to ground level.

Featuring the world’s largest loop, this Six Flags Magic Mountain coaster in Valenica, California catapults riders at 66 miles per hour before being sent into a massive 160-foot loop.

This high adrenaline coaster is packed with twist, turns and loops. Located at Sig Flags Fiesta Texas in San Antonio, Texas, riders reach top speeds of 70 miles per hour and must endure a 145-foot loop, a cobra roll, two corkscrews and even a zero gravity roll.

The first roller coaster to ever use floorless trains, this Busch Gardens Williamsburg coaster features two Immelmann loops, two vertical drops and a splashdown. The coaster also reaches a top height of 2,005 feet and a top speed of 71 miles per hour.

Located at the world famous Cedar Point in Sandusky, Ohio, this coaster sends riders on a terrifying 300 foot drop, two tunnels, three overbanked turns and reaches speeds up to 93 miles per hour.

We hope you have an electrifying time and enjoy these rides as much as we do. As always, remember to call on your friendly neighborhood Mr. Electric for any summer electrical needs.

Lately, I have been coming across lots of photos of cool applications of kitchen track lighting. So this week I thought I would share some of my favorites with you. I hope you find some inspiration below. Or, if not, I hope you at least enjoy seeing how relevant via Pinterest (Marcia Moore)

It’s not a huge, luxurious kitchen. It is something better: Real. Track lighting functions to illuminate kitchen tasks while accenting the wall. All is taken care of with one fixture. It’s the perfect solution in this kitchen full of well-used space.

2. For Gigantic Kitchens, Too

The lighting design pictured above calls attention to the right angles in the kitchen. It’s a metropolitan look that gives the room a sense of cohesion. Track lighting like this can also be used in kitchens with exposed beams. Using tracks to cross gaps or grades in the ceiling can be really cool.

4. Pendants and Spots, Spots and Pendants

Another new trend in kitchen track lighting is the flexible track. While this kind of track is generally not malleable by hand, a special track bending tool allows you to create a custom shape. I’m not sure who bent the track above into that nice curve, but it sure looks good in this real-life kitchen, which is complete with baby pictures on the fridge.

6. Wire Track Lighting

Kitchens like the one above make you see the brilliance of modern design. To put it simply, this kitchen is beautiful work of art, from the brushed metal ceiling to the glass tile to the granite to the smooth top range. To the track lighting! Can I hang out in here? FOREVER?! Muah ha ha. Ahem. Moving on.

7. Very High Ceiling

These very bright track lights look great with their blue glass shades. And they are task-oriented lights, a clear choice for the chef of the house. The aesthetic and functional dualism embodied by kitchen track lighting echoes the aesthetic/functional dualism of the culinary arts. It provides something you need and looks good while it does it.

9. Pendants Done Right

And here we have a lovely kitchen island situation. Notice that the island is dynamic. There’s a gas range for the chef and chairs for the kids. Quite a lot going on. So they had to be very deliberate and smart about the lighting. These white pendants are perfect. What was once utilitarian is now elegant – even graceful.

10. Kitchen Track Lighting Mash Up

Here we have a kitchen doing it all with track lighting. There are spot lights, pendants, and it’s even on a curved monorail. These contribute warm light to a comfortable environment, and they go well with the chandelier. Win.
