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.

An electric conduit is electrical tubing used for protection and routing of electrical wiring. They can be made from a variety of materials, such as: plastic, metal, fiber and fired clay, all depending on the purpose it is being used for. It is generally installed by electricians at the electrical equipment’s installation site. The regulations governing the conduits’ use, form and installation details are specified by the US National Electrical Code (NEC).

Conduit is used as a general term to describe any system that contains electrical conductors. The conduit systems are installed for the following reasons:

To operate as pull outlets for the conductors that are being installed Make 90° bends in conduit runs

Types of Conduits

Conduit systems are classified based on the material used to make the tubing, mechanical stiffness and wall thickness. The material is selected for mechanical protection and corrosion resistance after taking into consideration the cost factor. There are special guidelines to be followed for wiring equipment in hazardous areas that need prior approval. Based on these factors, we examine a few prominent conduits:

Form 35/5/85 ex. Appleton LB400M

The Form 35 is used for malleable iron unilets as they have high tensile strength and ductility along with high corrosion and shock resistance. With the easy inbuilt rollers of type C (1-1/4” thru 4”) and type LB (1-1/4” thru 4”), these type of conduits help eliminate the damage when cable is pulled through the hubs. Form 5 has inbuilt rollers on all 11⁄4 to 4 C and LB bodies to facilitate wire pulling.

Form 7 ex. Crouse hind LB37

The Form 7 ex. Crouse hind LB37 is compatible with rigid and intermediate conduits for indoor as well as outdoor installation. It is made of cast iron or cast aluminium for a long life. It is extremely suitable for compact installations with rigidly threaded conduits of various shapes and sizes. The Form 7 has an exclusive snap tight and wedgenut cover attachment to provide clear, unhindered cover opening.

Mogul ex. Appleton BLB400m

The Mogul ex. Appleton BLB400m has a large body size that facilitates pulling of large and heavy conductors and are used as cast covers for providing additional wiring area. These are best used for pulling straight, 45° or 90° angle turns as well as for making taps and splices.

Form 8 ex. Crouse LB38

The Form 8 ex. Crouse LB38 is a 1” rigidly threaded conduit without cover and gasket made of Feraloy iron alloy. It is useful for indoor and outdoor use and comes in sizes ½” through 4”.

Form 9 ex. Crouse LB39

If you’ve ever seen “National Lampoon’s Christmas Vacation,” you’ll know that Clark Griswold’s perception of Christmas decorating is a bit extreme.  Although that movie is comical, in reality electrical safety is no laughing matter, and an electrical fire can ruin your holidays instantly.  Here are a few holiday decorating safety tips.
