We hear a lot about LEDs these days, but is there a place in the market for their fancier, pricier cousins, the OLEDs? Organic light emitting diodes have yet to find a niche in the market, but if and when they do, they’ll have to overcome stiff competition…

This summer, soccer’s about more than just winning games. A group of young innovators have started producing a new kind of soccer ball that can generate and store electrical power when kicked around. This is a huge breakthrough for families who don’t have reliable access to power…Image via EarthTechling

To most people, circuit panels are the first place they go when power fails to a room.  The loud click heard when a space heater or hair dryer overloads a circuit usually calls for a quick trip to flip a circuit breaker back on.  Every building depends on the circuit panel for safety and electrical management for the home.  The electrical panel for your home, along with the attached circuit breaker, serves to delegate power throughout the home.  By splitting up power demands, it prevents overloads in separate rooms and isolates individual features and appliances.

You may be wondering why we need to split up circuits the way we do.  If all of our devices operate on 120 volts, why do we need separate circuits?  The answer has to do with the physical quirks of wiring.  You see, while everything operates off of the 120 volts delivered by your home’s wiring, the power demands are different for each device.  As power is applied to a circuit, current flows over the wiring and heats it up.  The higher your power demands, the more current is flowing through the wires.

The wires in your home can only handle a set amount of current (most circuits are 20-amp circuits) before they overheat and begin to ignite insulation around them.  If you placed every light, appliance, and TV in your home on the same electrical circuit, you’d reach this thermal limit almost immediately.  To prevent his, we install circuit breakers to help separate energy demands to specific rooms.  We also separate the energy load to create special appliance circuits.  This is why your HVAC unit is on a separate circuit from your kitchen and your laundry room.  Appliance circuits use thicker wires which are designed to handle higher electrical loads.  High current circuits are expensive, so homes are designed to use them sparingly.

This is also why you should only ever replace breakers and fuses with new units that have the same tolerance.  Circuit breakers are designed to be the weakest link in a system.  They must trip before anything on the circuit itself would fail.  This safety feature means that the breaker will trip before wiring overheats or appliances are damaged by high-current draw.  If you do need to replace a breaker, always match it with the same current-rating.

Power surges are another reason we separate circuits in a home.  Whenever a load is applied to the system (you turn on a hair dryer, electrical appliance, or even a lamp) inrush current is also applied.  Inrush-current is the initial surge of power that occurs when current is increased.  Extra power is applied across the system, which causes a risk of electrical damage when a high-power device is applied to a low-power circuits.  To mitigate this, high-load motors such as those in power tools, HVAC systems, and other appliances are plugged into special appliance circuits.  This is also why you should plug sensitive low-voltage electronics into surge protectors.

Sometimes electrical panels can wear out.  While the signs are clear when you know what to look for, without experience you have no way of knowing if it’s time to replace your panel.  Get an inspection for your electrical panel if:

If, however, you happen to notice one of two logos, Federal Pacific Electric (FPE) or Zinsco, you should call for a replacement immediately.  These older models of electrical panels are unsafe and should be replaced quickly.

Sometimes the smallest residential electrical issue can be a  big headache. When outlets trip, for example, there are generally several electrical devices or appliances being used in one electrical zone. Then POP! No more power.

GFCIs May Be to Blame

Ground fault circuit interrupters (GFCIs) are outlets that trip themselves when they detect certain problems. They are designed to prevent electrical shock and other potential dangerous accidents, which is why they are required in bathrooms, kitchens, garages, outdoor areas, and unfinished areas .

Many homes have GFCIs in the required areas but not all over the house. So it’s common that electrical circuits will start at the GFCI and flow “downstream” to other outlets that are required to be GFCI’s. While this provides a level of protection for the entire circuit, a GFCI trip in the bathroom, for example, may take down an outlet in  another bathroom.  You would need  to identify the GFCI outlet where the trip happened and reset it. .  This can be a frustrating and time consuming process.

Every home uses energy in one form or the other; and in most instances, this electricity comes from the power grid. Statistics indicate that almost 50% of a home’s energy is used by its HVAC systems while about 12% goes into the lighting. Most property owners presume that all the energy-efficiency upgrades happen through various home improvement upgrades such as replacement of wooden windows and doors with energy-efficient 2 or 3-paned vinyl windows etc.

While these changes do add to the energy-efficiency of your home, there are a number of electrical systems and maintenance upgrades that can significantly improve your energy usage, such as:

It’s not uncommon for us to occasionally leave the lights on when we leave a room. Or there may be times when we leave the deck, patio or poolscapes lights on all night with the security aspect in view. These types of habits can become a significant energy drain, but there is a way to curb that. We can install motion sensor lighting in the exterior spaces of your home; the lights will get switched on only when the sensor picks up any movement within its range. This helps you save energy without compromising on the safety factor in any way.

Most people don’t realise that their local electrician can help them when they are upgrading to energy efficient appliances. The fact of the matter is that simply replacing older appliances with ones that have high energy star ratings may not always help them reduce their electricity bills.

When you upgrade the appliances in your home such as air-conditioners, dryers, dishwashers and washing machines etc., these appliances tend to need a higher wattage compared to the older ones; this means the upgrade may actually strain the circuit breakers and your electrical system. It’s important to get a skilled electrician to come and check whether the existing wiring and system is built to bear the higher electrical loads that the newer, advanced systems need.

Inadequate or improper insulation is one more major sources of energy loss on most properties. And if you are considering a home renovation/remodelling/extension project, it’s a good idea to upgrade the insulation in your house as well.

Today, many property owners are quite committed to opting for eco-friendly alternatives to many materials and systems. If you feel you want to reduce your carbon footprint, you might want to consider installing solar panels in your home. This can significantly reduce your reliance on grid power.

Upgrading appliances or making major electrical upgrades can sometimes prove to be an expensive proposition and may not fit into everyone’s budget. This is why it’s important to know how to make some smaller changes that will also add to your home’s energy-efficiency. Some things that can make a big difference are:
