Most new buildings are now using a variety of electrical and electronic equipment. As such, the contractors have to design a wiring schematic that will deliver power to a wide and diverse range of devices that include traditional and modern electrical loads.  The wiring must also provide a means of supplying power to the monitoring and control devices such as wireless sensors, thermostats, automatic light controls, thermostats, the IoT, and other web-based technologies.

The electrical requirements will vary from one building to another and may include a combination of the following components:

The type and use of a building structure influences the type of wiring to use. And the building owner and electrical contractor should consider current and future power requirements when determining the size of conductors, raceways, protective gear and other necessities.

Let’s say your teen is using an electric drill outside and standing with bare feet in a puddle. Not a good idea. Let’s say the drill malfunctions and leaks electricity out of its proper circuitry. Electricity takes the path of least resistance, which just might be from the drill, along arms and legs, and into the puddle. If the drill were plugged into an ordinary outlet, this could be a fatal accident.

In recent years, the National Electric Code has included requirements for special safety outlets where such accidents could happen. These special outlets are called “GFIs” (Ground Fault Interrupters) or “GFCIs” (Ground Fault Circuit Interrupters) — two different names for the same thing. They are required by the National Electric Code in garages, kitchens, bathrooms, pools, spas, and in some other outdoor areas where water could be present. The Electric Connection, your local Glendale electrician, can check all of your outlets for you and replace or install new GFCI’s.

A GFI, or safety outlet, detects that the current in an appliance is no longer flowing in its proper circuit. It shuts off the current within milliseconds. In the case of our teen, if the drill were plugged into a safety outlet, electrocution would be avoided — a life saved.

GFIs look different from ordinary outlets. They have two buttons labeled “Test” and “Reset.” You can check that the outlet will cut off current when needed for safety by pressing “Test.” Test should shut off current to the outlet so that the outlet no longer provides power. After the test, you can restore current to the outlet by pressing “Reset.”

Newer GFIs also have a tiny green indicator light that tells you that it’s providing power. This is a handy feature when you conduct your test. It’s also handy because from time to time, safety outlets may be triggered without your knowledge and may no longer be providing power. The absence of the green light will alert you to this situation.

A Downside

This is the downside of safety outlets — they can be tripped without your realizing, or they can become faulty and can trip repeatedly for no reason. Let’s say you have an electric toothbrush charger plugged into a safety outlet in your bathroom. The outlet has somehow been tripped and no longer provides power. If it’s equipped with a green indicator light, the light will be off. In any case, if it’s lost power, press “Reset” and power should be restored.

Another possibility is that an outlet in a kitchen, bathroom, garage, or outdoor area is not a safety outlet but is “protected” by a GFI elsewhere in the circuitry. If a non-safety outlet in your house has lost power, you can check for this situation by making sure that all the GFIs in your kitchens, bathrooms, and other areas have not been tripped and are still providing power.

Home Safety Check

Check that your kitchens, bathrooms, garage, and outdoor areas are equipped with working GFIs. (Refrigerators are incompatible with safety outlets and should not be plugged into one nor protected by safety outlets elsewhere in the circuitry.) If you have GFIs, remember that they have a limited lifespan, so press the Test button of each at least once a month to check that they shut off power as designed.

If your home doesn’t have safety outlets or they are no longer working, call a qualified electrician to get an estimate for installation. GFIs are a relatively inexpensive investment in your family’s safety.

Smart technology is poised to take over the home appliance market. We already have smart thermostats, smart lighting and even smart refrigerators. If that's not enough for you, there are some new contenders on the market that allow you to turn any electrical device in the home into a smart item. The best part is that it's a simple DIY experience – no need to find an electrician to hook it up. It’s the smart plug, a small box that you plug into your home's outlets. From there, you can use your smart phone to control whatever light, television or other electronic appliance routed through the smart plug. Read on to learn more about these remarkable efficiency devices.

Control and Monitor Your Electronics

There are a variety of smart plug options on the market: The Satechi IQ Plug, the Belkin WeMo Insight Switch, the D-Link Wi-Fi Smart Plug and the Valta Starter Kit, among others. The cost and functionality of the different brands vary, but they all operate on a similar principle – allowing you to set schedules and remotely control whatever device you choose.

The smart plugs connect to your phone via Bluetooth or wireless Internet, so you can switch them on or off from anywhere in the home – or even from the other side of the country if you have an internet-optimized model. You can also program schedules so the plug automatically activates an appliance at appointed times – turning a coffee maker on first thing in the morning, for example, or switching on a space heater before you go to bed in a chilly part of the house.

Retro Meets Modern

The upshot is that there's no need to wait for cutting-edge smart devices to come out to keep your home on the cutting edge of technology. Imagine impressing your neighbor by demonstrating the new smart functionality of a retro 1950s television, or your old Victrola vinyl player.

Smart plugs also monitor how much electricity a given device uses and when, so you can make informed choices about increasing your energy efficiency though disaggregation, breaking it down appliance by appliance. You can also save energy by using the smart plug to turn off the power to devices when you aren't actively using them, preventing your electricity bills from skyrocketing due to always-on settings or “energy vampires.”

Savings and Control All at Once

If you have additional questions about smart plugs and how they work, find an electrician who can show you their utility and functionality. With surprisingly little effort, you can harness their power to save energy and control devices all throughout your home.

If you've ever experienced a partial power outage, you know just how weird it seems. You thought you had a steady stream of power, so if it was compromised, you’d experience less power throughout the house rather than half on, half off, right? That’s not always the way it works. From the viewpoint of an engineer or a professional electrician, a partial power outage would be better described as a phase loss.

Although the bulk of your appliances run on 110 volts, your stove and laundry use 220 volts, as does your water heater ad HVAC system. That extra amount of power isn't a doubling of your electric flow, but full use of what's available. Your lights and appliances are actually running on half your available electric source in order to cut your bill by using the electricity more efficiently. The power flow coming into your home is actually two sets of 110 volts, designated as “phase 1” and “phase 2” that share a ground to safely eliminate excess power.

What that means in layman’s terms is that you have two distinct power sources. They run together in what appears as a single line, but that’s why you have a breaker box. There’s more going on in that box than just safety circuits to prevent overflow. It directs the power according to your needs.

In the breaker box, that power that is supplied is magnified exponentially. The full 220 volts is sent to those few appliances that need it. The rest of your home, the lights, outlets, television and hair dryer, well, they are actually only running on one phase, or half the available power. That’s why you think in terms of 110 volts, because your plug-in electric units only use 110 volts.

Emergency power systems are vital for any business or IT operation to keep mission critical systems operational and avoid equipment damage during a power failure. Don Jennings, President of Network Computing Technologies discusses the value of emergency power systems in preventing the loss of electricity to data sources and other IT operations such as servers, point of sale systems, PC’s, routers, switches, telecommunications, and other equipment. The Indoor Generator offers IT professionals an affordable solution that provides hours of backup power at a fraction of the cost of current UPS products on the market.
