The incandescent, tungsten, or filament light bulb as it is known, isn’t energy-efficient at all. It converts very little of the electricity it uses into light, most of it is wasted as heat, which also tends to shorten the life of light fittings and shades.
The other downside of an incandescent light bulb is its short life. The typical incandescent light bulb (known as GLS – or general lighting service) will last 1,000 hours or one year’s typical use. Turning them on and off regularly shortens their lives even more.
Incandescent light bulbs are being phased out by the end of 2011 under a government initiative.
A circuit breaker is a switch that automatically interrupts electrical flow in a circuit in case of an overload or short. Homes built or rewired since the mid-1960s use circuit breakers to monitor the electricity coming into the home. By sensing and responding to conditions where the normal load current is exceeded, called overcurrent, circuit breakers help protect your home and family from electric shock and fire. While installation or replacement of circuit breakers is best left to licensed professionals due to electrical code requirements and the dangers of electric shock, understanding the different types of circuit breakers can help you make the right selection when you need new circuit breakers for your home.
Standard circuit breakers monitor the flow of electricity as it enters your home and makes its way through your electrical wiring system to outlets, light fixtures, appliances and electronics. As long as the electrical current operates within levels determined by the breaker’s ratings, the flow of electricity continues unhindered. However, in the event of an overload or short circuit — caused when a hot wire touches a neutral wire, ground wire or another hot wire — the breaker trips and breaks the current to prevent wires from overheating and diminish the potential for electrical fires.
• Single-pole breakers protect one energized wire and supply 120V to a circuit.
– Standard single-pole breakers are generally 15 or 20 amps.
– Single-pole units, which occupy one slot on a breaker panel, are the most common breakers
in a home.
– Three types of single-pole breakers are available:
• Full size, which is 1 in. wide;
• Half size, which is 1/2 in. wide; and
• Twin or tandem, which is 1 in. wide, has two switches and controls two circuits.
• Double-pole breakers typically occupy two slots on a breaker panel and consist of two
single-pole breakers with one handle and a shared trip mechanism. They
– Supply 120V/240V or 240V to a circuit;
– Protect two energized wires;
– Range in capacity from 15 to 200 amps; and
– Are required for large appliances like dryers and water heaters.
Ground fault circuit interrupter (GFCI) circuit breakers cut power to the circuit when they are tripped by an overload of current, a short circuit or a line-to-ground fault, which occurs when an unwanted path forms between an electrical current and a grounded element. All GFCI breakers have test buttons on the front and coiled wires. They function in the same way as GFCI receptacles, but protect an entire circuit, eliminating the need for GFCI receptacles on that circuit. Both GFCI circuits and receptacles should be installed as recommended by the National Electrical Code (NEC). GFCIs are:
• Required in potentially wet locations such as kitchens, bathrooms, outdoor areas,
basements and garages; and
