For the average homeowner, electrical panels are not very well understood. Since the job of an electrical panel is to deliver electricity, the common assumption is that if you need more electricity to support your household, you should just be able to add more circuits. This is incorrect, though.

This is only part of your electrical panel’s job. It also acts as a safety device, channeling the electrical flow into circuits so your home gets the amount of electricity that’s allowed by the panel. If your home doesn’t have enough electricity, then it’s time to upgrade your electrical panel, but how do you know when this time has come?

Have you noticed any lights in your home that flicker, dim, or brown out when you turn on major appliances such as your dishwasher or microwave? This is a sign that the draw on your system is too strong, and that you would benefit from adding more amps to your electrical box.

If you have multiple circuit breakers that trip on a regular basis, this is probably a sign that you don’t have enough power coming into your home. If you’re constantly flipping circuit breakers back on in your electrical panel, you could very well need an upgrade.

This is actually an outdated method of managing the electricity in your home. In fact, it can be downright dangerous. Many homeowner’s insurance companies won’t even insure homes that still have fuse boxes instead of an electrical panel. Fuses simply can’t provide the amount of power that the average home needs. The best thing you can do is upgrade your fuse box to a standard electrical panel as soon as possible.

Around the world, every city offers something different. Though they all have hustle and bustle, lots of buildings, and usually traffic, when you’re on their streets you would never mistake San Francisco for Cairo, Toronto for Tokyo, or Berlin for Rio de Janeiro. But what about from space? During the day, these cities tend to blend in with their surrounding countryside. However, when lit up at night, it’s easy to see how varied these cities can be.

Is it possible to tell anything about the life and culture of our cities when viewing their lights from above? You might be surprised at how much.

Landmarks

Can you guess which cultural icon jumps out of this landscape?

Now, take a look at this photograph of Denver, a much newer city. The streets are mapped out in a much more orderly, grid-like way, aligned North-South and East-West.

The majority of urban areas in Tokyo use green mercury vapor lamps. Only the most newly built areas glow the standard orange.

Development

When examining a city’s lights from above, you can also learn about development, community growth, and infrastructure. Check out this unique photo of two cities from two countries side-by-side – the border towns Cuidad Juarez, Mexico and El Paso, Texas.
