When it comes to your home's electrical system, you don't want to overestimate your capabilities by attempting a repair that should be handled by a professional. The risks associated with a faulty electrical system are many, ranging from damage to your property to life-threatening injuries.

However, one simple repair that should be easy enough for the average homeowner is replacing a fuse or a breaker.

Homes that feature a breaker have a series of "on" or "off" switches that will trip when a surge is too powerful. Fuse boxes will feature small, bolt-like fuses that need to be replaced after a surge blows the device out.

Breakers and fuses are designed to protect the wires' ampacity rating and the devices and appliances that they are connected to. Where a breaker will simply switch off when wiring is overwhelmed, fuses are built to a specific size that will moderate the amount of power that goes to a specific source. When a fuse constantly blows or a breaker is continually tripping, some homeowners think it's because they have invested in the wrong size for the wiring. To correct this issue, some individuals will try inserting larger fuses or breakers. In almost all instances, this will only cause more problems.

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:

Love is in the air! Fall officially began last week, so we are in the throes of the autumn wedding season. Although the summer months have traditionally been the most popular for weddings, autumn weddings have steadily risen in popularity and nowadays, you’re just as likely to receive an orange maple leaf save-the-date as you are a frilly invite with a flower border.

But as we all (should have) learned in elementary school, when the seasons change, the angle of sunlight touching the earth changes as well, resulting in a different quality and duration of sunlight. While many people prefer the more “golden” tones of autumn afternoons (especially photographers!), it can certainly be challenging to keep your special day well-lit when the sun begins to set. But never fear! Here is a list of four ways lighting can save the day on your big day.

If you can, hire a lighting designer for your wedding.

Whether you want a romantic vibe, like in the picture, or more of a warm, casual family feel, lighting can make a huge difference on how successful you are in achieving the aura you desire. You will want to look into professional lighting design, especially if your wedding takes place outside. Many venues have pre-approved lighting designers familiar with their codes, so make sure to find out when venue-hunting.

But if hiring a lighting designer is these awesome DIY wedding lighting tips from the blog at Wedding Window.

It’s incredibly easy to forget about “minor details” like lighting while planning your wedding, but you can go nuts trying to come up with last-minute lighting solutions. Since lighting has such a big impact every part of the wedding, make it a priority!

3. Make a list early on of things that need to be well-lit, and plan accordingly.

Do you want your new monogram spotlighted on the wall at your reception? Or pinhole light above your wedding cake or centerpieces? Maybe fun, moving lights for the ceiling above the dance floor?

Research some of the lighting elements that have worked well at past weddings and make a list of everything you want at yours. It’s okay if you have to scrap some of your ideas, but the process of writing it out will help you make sure you don’t miss anything you’ll regret later.

If you’re doing your own lighting, this step is crucial to planning for what kinds of lights you want where, and what crafting you need to finish beforehand. Taking the time to plan ahead will save you all kinds of trouble at game time.
