There are two things that regulate the power circuits in your home: fuses and breakers. Breakers are designed to turn off when they are using too much power, as that will prevent the wiring in your home from burning out. Fuses serve much the same role, though they don’t trip — they simply burn out when they are overloaded. Knowing how to replace fuses and breakers is important, as it will help you to keep the power in your home on at all times.

See, quick and easy to replace both fuse and breakers! If you need an electrician in Austin to come out and help you repair electricity problems in your home, call Bryant Electric Service today at 512-402-8587. One of our friendly service members will answer any questions you may have!

Technology giant Google made its start as a search engine, subsequently branching into email, cloud storage, advertising and so much more. Now the company from Mountain View is surging forward with a new application, promising to tell consumers if their roofs are suitable for installing solar panels. The program, called Project Sunroof, works in conjunction with Google Maps to analyze your roof's size, orientation and shade levels to tell you at a glance how much solar energy you could get from it. Read on to learn more about how this convenient software works and how it can help you.

A Mix Between a Solar Electrician and a Search Engine

The program is simple to use – all you have to do is enter your address, and Google does the rest. According to the company, the program analyzes all of the following to determine how much sunlight you can soak up:

The program also provides information about what tax credits are available in your area as well as the local rules regarding selling solar energy back to the utility company when your panels are producing more than you need. It then spits out a recommended installation size, which you can modify based on how much electricity you actually consume according to your average electricity bill.

Pay Nothing and Start Saving Today

Google's entry into the solar market comes at a time when the options for solar are expanding, including the ability to lease panels from solar companies and enjoy savings on your utility bills while paying nothing for the installation and setup. A good setup can last for 30 years or more, with little to no maintenance from an electrician once the installation is completed.

Of course, solar isn't for everybody, since many roofs might be too shaded or otherwise not suitable, and some states still don't have good solar policies. Therefore, Project Sunroof can be a good place to get started to see if your house is a prospect before you even call a solar electrician. Currently, the program is working on a trial basis in Boston, San Francisco and Fresno, with more cities sure to be on the way.

Don't Forget About Human Experts Just Yet

Of course, even a technology company as powerful and ubiquitous as Google can't fully substitute for an experienced solar technician when it comes to analyzing how you can benefit from panels. If a Google query indicates that your home is a good candidate, have a qualified electrician or solar expert make the final determination and help you decide if solar panels are right for you.

An automatic transfer switch consists of an electrical power control device that reroutes electricity under certain power conditions. It enables the safe switching of power from one source to another. Consequently, this ensures a safe and reliable transfer of power while minimizing the risks of fire, damage, or back feeding of power to the utility lines.

An ATS ensures continuity of power to the load. However, the time between loss of power in the utility line and the time the load is connected to the alternative power source remains critical in some applications. For example, a power loss for a few seconds is unacceptable in some hospitals or with emergency equipment. In some of these installations, an intermediate power supply is utilized. These include the battery-based inverter or UPS power to fill the gap between the loss of power and connection to the generator power.

Advanced ATS devices may have the ability to detect the voltage dips characteristic of power failures and automatically start the generator before the utility power goes off completely.

Consumers need to ensure that the ATS will have adequate capacity to handle the generator power. Things to consider include the voltage rating, continuous current rating, and type of load. In addition, consider the mode of transfer, desired transfer time delay, ATS style, and more.

The four main categories of ATS devices are defined by the following transition modes.

Open-transition: The open transaction mode of operation disconnects the primary power before connecting the power from the secondary source. This break-before-make operation means a short duration when there is no connection to either of the power sources.

Fast closed-transition: The ATS is based on the make-before-break switching operation. It parallels the two supplies for about 100 milliseconds after which it disconnects one of the sources. This operation ensures that the load is never disconnected from power.

Soft closed-transition: The soft closed-transition transfer synchronizes generator power with the utility line and then transfers the load from the utility to the generator. When transferring the load back to the utility, follow a similar process.  In this case, the generator output slowly decreases until completely off.

Sub-cycle transfer: These are based on semiconductor switches and are the fastest automatic transfer switches. Upon detecting a power failure, the ATS transfers the load to the other source within the first one-quarter of the electrical cycle. This ensures no power interruption to the load. Sub-cycle ATS devices are the most complex and expensive compared to those using mechanical switches.

Since consumers may not have all the necessary technical knowledge to choose the correct application, it can be a good idea to hire a qualified electrical contractor to select the correct sizing and installation.

Electrical wiring and materials have improved significantly over the years, but if you live in a house in which the wiring was laid a long time ago, there may be some risks involved. It is worth checking to see whether everything is as it should be.

Electricity is normally out of sight and out of mind because the cables are hidden in the walls and in switches and sockets. As a result, we rarely check the condition of our electrical installations. Faulty and aging wiring can cause electrical fires, but you can avoid this by having your electrician check them for you.

There are clear indications that can make it easier to identify aging cables. Any cables that are coated in black rubber will be quite old as they were phased out in the 1960s; the same applies to fuse boxes with wooden backs and cast-iron switches. These were also phased out in the 1960s.

During your inspection, you may see wires that look old but are intact. These will likely be safe to use. You will need to check any connections wrapped in friction tape to ensure that the tape is not unraveling or frayed. If the tape is damaged, turn off the circuit and replace it with new tape.

The biggest disadvantage with most old wires is that they do not normally implement ground wires. This may result in a person becoming the path to the ground and being electrocuted if there happens to be a short in an appliance.
