GFCIs or ground fault circuit interrupters are safety devices that have been extremely effective in reducing the total number of home electrocutions by almost 50%, in Australia. Most new homes and businesses now have these devices installed in locations where water is present in and around the premises. It’s important that electrical installations in outdoor locations be protected from wind and rain; that’s the one way to prevent shock hazards.

Before we understand what a GFCI is, let’s understand what a ground fault is. It is the unintentional flow of electrical current between the source and any grounded surface. If the electrical installation isn’t properly protected, an individual that comes into contact with an energised part can suffer an electrical shock.

For instance, if the person is holding any deteriorated electrical cord attached to the hair dryer, and it happens to touch a plumbing fixture they are using, they can get electrocuted and will suffer a painful shock.

This small receptacle has “test” & “retest” buttons on it. It may sometimes be built into circuit breakers that are installed in the main electrical panels. When electricians are conducting an electrical audit, they also test whether the GFCIs are functioning properly. They might also recommend that you get GFCIs installed in the vicinity of plumbing fixtures.

These are extremely useful electrical safety devices which trip the electrical circuits in case they detect any leakage current or ground fault. An individual that’s become the pathway for a leaked current can get a severe shock or will get electrocuted. It is important to get GFCIs installed in any outdoor or indoor areas where you feel that water might come in contact with the electrical installations or fixtures you have on your property.

Ideally, the areas where GFCIs should be installed include:

It is important that these devices be checked with regularity. If you have opted for an electrical maintenance contract, the electricians will ensure that the GFCIs are checked along with all the other installations; this will help confirm they are working as they should and that they provide the necessary safety to those living or working on your premises. You can also test the GFCIs on your property, by following these basic steps:

If you aren’t too sure about whether you have GFCIs installed at the right points on your property, call in your local electrician. They will inspect all the fixtures and inform you if GFCIs have to be installed in any specific rooms or outdoor spaces. Aside from this, they will also audit the rest of the installations and tell you if any upgrades are required.

Power failures are frustrating and difficult in ways people don't always understand. Being used to having a steady power source, you don't always think of the full effects of a power outage. If the power outage is short, it can be fun to have a cookout on a grill and a family dinner by candlelight. The TV doesn't work, so you might find a movie to watch on your computer, until you realize you don't have enough battery life and there is no way to recharge it. You want to call the power company to find out what is going on, but they put you on hold and again, there's no way to charge your phone battery. You might decide to go out to eat or even stay with friends, but you, your spouse, and your children need to bathe first and there's no hot water.

There are some jobs out there that you can very well do all on your own. But there are others that need the guidance and experience of a certified electrician in Gaithersburg.

In some of our previous posts, you’ve likely seen our experts mention the presence of “ungrounded” outlets in homes and buildings. But what exactly makes an ungrounded outlet such a negative? Are they dangerous? Our certified electricians come to you today with answers to the real important questions regarding ungrounded outlets!

If you have ungrounded outlets and need an outlet upgrade, contact us today!

Ungrounded outlets are easily identified by simply taking a look at the face of the outlet (where you plug things in). On nearly all modern homes, there should be three holes. Two are the vertical slits, and one roundish one located underneath the pair of vertical ones. That’s a grounded outlet, which have been required by electrical safety standards for all structures since the mid-1960s.

Ungrounded outlets lack the third hole, the roundish one on the lower portion where the, somewhat obviously, ground plug goes.

To understand the why, you kind of have to understand what a grounded outlet does. The two vertical slots represent both a “hot” wire, and a “neutral” wire. The ground wire in a grounded outlet ties into the neutral vertical slot. Why the redundancy? Well, it acts like a failsafe. Should anything go awry with your outlet, such as a short, the renegade electricity simply travels safely along the ground wire back to the panel. Without the ground wire, that electricity can channel into materials, such as fabrics located close to the outlet, or a very unlucky person.

Is it dangerous in that it might jump out and bite you? No. Is it dangerous in that it dramatically increases personal and property risk? Yes, absolutely. Ungrounded outlets increase the chance of:

We’ve encountered a few arguments over the years about the safety of ungrounded outlets. Like how they were used just fine in the past, or how the home that has them hasn’t “burned down yet”, etc. Well, that’s just the thing. Yet.

We haven’t been hit by a car, but that doesn’t mean we should go walking down the center of a busy highway at midnight. Grounded outlets became a standard in electrical code for a reason. They prevent possible problems that homes consistently encountered in the past. It’s all about preparedness and prevention!

So to conclude, are ungrounded outlets dangerous? Yes, they represent a very real potential risk.

If you’re like me, you have a favorable reaction to yachts, perhaps without ever having stepped foot on one. I have absolutely no idea how I will one day acquire a yacht. All I know is that yachts and I are destined to be together some way, somehow. This amorous examination of yacht lighting exists, yes, because there are interesting things to note about yacht lighting design, but, if I’m totally honest, we’re in the dog days of summer; I’m landlocked; and I want to stare at yachts. Do you want to stare at yachts, too? Let’s stare at yachts in all their luminous glory.

1. In A Word, Yes. 

I am sucker for underwater lights. In pools, in little water features and ponds, they just make me smile. But beaming into a foreign sea from the hull of a yacht? I am slain (in a good way). Of course, that’s not the only amazing thing about the yacht lighting situation above. While the lights are illuminating the sea on either side of our vessel, whaddaya say we project the sea life around us onto this huge sail? OK, great!

I mean, seriously?! Are you seriously watching the sea life around your yacht as it’s projected onto a giant screen in the middle of the beautiful sea with starlight and moonlight above you and light beams shooting out of either side of your vessel? Yes? Well OK, then. I guess I would, too, if I were you.

2. Outdoor Recessed Lights

What an amazing night time mood these recessed lights lend this yacht. I love the way the fixtures form scallops of light along the side of the cabin, especially because the reflective surface of the yacht amplifies the light levels. Very nice via Charter World

And it also says, Come hither thou and hangeth out on me. Basically, these lighting designers have gotten it right. What looks better against the soft night sky than lights with a via Charter World

Those recessed light fixtures with single and multiple lamps are a great choice for this yacht living room/control center/spaceship dashboard. The top level is evenly lit, and the lower level, with its crisp light, invites the eye and the whole body, actually. Take me to Greenland, Captain! If you need me, I will be luxuriating.
