If you’re ever a contestant on Jeopardy and you’re asked what a GFCI is, you can respond by saying, “What is a ground fault circuit interrupter.” But knowing what GFCI stands for doesn’t mean you understand what it is. You’re not alone—the average homeowner is unaware of what a ground fault circuit interrupter does, but when your house’s ground fault is compromised, it can put the entire property, and your family, in danger.

A ground fault is an electrical path between a power source and a grounded surface. While all electrical devices and appliances are “grounded” to ensure they can be safely operated, devices can still lose their grounding and divert electrical currents to the nearest channel that provides a path to the ground: you. That’s why you need ground fault circuit interrupters in your home.

You’ve probably seen GFCI and never given them a second thought. They’re a common safety feature found on your electrical outlets that can be identified as two small buttons located in between the two sockets, the GFCI’s function is to constantly monitor the power current flowing through a circuit. At the first sign of a discrepancy between the current flowing into the outlet and the return current, it intervenes by shutting off the power to the outlet.

Sometimes that light that seems to be acting strange lately is more than just a fluke. It is a precursor to a bigger problem and it should be looked at by a professional right away. Little things like a popping breaker or a funky electrical smell are all signs you need a Pasadena electrician to come out and do some investigating. Not every problem is something small and meaningless. Those little electrical warning signs are often indicators there is something happening behind the walls of your home that you cannot see. It is imperative you get an electrician out as soon as possible to determine what the underlying cause is. The Electric Connection has a team of qualified electricians who are here to help.

If you are not sure what actually qualifies as an electrical emergency, this should help.

1-Anytime there is any smoking, crackling or visible signs like black streaks around an outlet, you need to call an electrician. Pasadena homeowners should consider this an emergency and call immediately. While you are waiting for service, do not use the outlet.

2-A breaker that seems to trip frequently is not an emergency, but it does warrant a look from a certified electrician. It may be weak or overloaded. If it is weak, it will need to be replaced.

3-Light fixtures that seem to work sporadically should always be checked out by an electrician. A loose wire could be causing a faulty connection. This can lead to an electrical fire. If you notice bulbs are constantly blowing in a fixture, it should be investigated as well.

4-An outlet that isn’t working properly may be improperly wired. This is something your electrician can take care of for you before it becomes a serious problem.

If you have experienced any of these issues or would just like an electrical safety inspection, give The Electric Connection a call today.

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.
