If you have a lot of appliances running at once,  you can actually increase your chance of having a surge. When high-powered electrical devices such as AC units and refrigerators are working at peak capacity, it takes a lot of energy to keep their motors and compressors going. This high demand can upset the steady voltage flow through your electrical system.

You should also unplug your important appliances during a power outage. There is often a surge when the electricity comes back on.

Additionally, consider a surge protection device which goes in the electric panel where the circuit breakers or fuses are located. The suppressor will channel the extra electricity during the power surge and prevent it from getting into your main system. If you live in an area that experiences a lot of storms, a lightning rod might be a good idea to mitigate the damage of a direct strike. Finally, make sure your homeowner's policy insures you in case a surge does knock out your devices, despite your best efforts to protect them.

Why do breakers trip? Have you ever turned on the vacuum or started the microwave while the toaster was in operation and experienced a tripped breaker? If you have ever dealt with a breaker that trips, you are probably wondering why it happened and want to know what that means for the safety of your home. An electrician in Pasadena is here to explain. You can learn more by calling The Electric Connection.

First of all, it is important to explain what a tripped breaker really is. Your breaker panel is probably located outside or in a hallway or basement area. When a breaker trips, it cuts off all flow of electricity to the outlets and light fixtures that the particular breaker supplies electricity to. When looking at the breaker panel, the tripped breaker will be slightly in the middle instead of all the way left or right. An orange bar is usually used to indicate which breaker has tripped.

As far as why the breaker trips, there are 3 main reasons • Short Circuit

An overloaded circuit is probably one of the most common reasons. If your breaker isn’t powerful enough to run several appliances at once, like the microwave, vacuum and toaster, it becomes overloaded and shuts down. You can address this by distributing your electrical draw to different outlets that are run by different breakers or by having your Pasadena electrical system investigated. You may be in need of additional breakers. A ground fault or short circuit are much more dangerous than an overloaded circuit. Breakers that have bare wires or a bad connection can cause fires. If you don’t see anything out of the ordinary, but are still having trouble with a tripping breaker, give the folks at The Electric Connection a call.

Understanding common household light bulb shapes, sizes, and styles is important whether you’re converting outdated incandescent fixtures into energy-efficient ones or using LED bulbs for new-construction applications. Every light bulb has identifying characteristics that are represented by a letter or series of letters and a number; these are known as light bulb codes. The letter or letters in a bulb code indicate either shape or special features such as reflector type. Numbers in a bulb code indicate size in millimeters or eighths of an inch. These codes will tell you if a bulb will fit in your fixture and if it’s the right shape.

For every light fixture or application, there’s going to be a specific bulb or light bulb shape that will fit best and provide the right type of light. If you understand bulb codes, it’s easy to look at a light fixture and know right away what kind of bulb you’ll need.

Let’s talk about light bulb groups, their bulb codes, and what applications those bulbs are typically used for.

Standard/arbitrary (A) bulbs are the most widely used and thought of when it comes to household lighting. These bulbs work well for a variety of applications, such as ceiling lights, lamps, vanity lights, kitchen lights, closet lights, porch light fixtures, and so many more.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

A15 bulb: 15/8 = 1-7/8″ diameter

A19 bulb: 19/8 = 2-3/8″ diameter

A21 bulb: 21/8 = 2-5/8″ diameter

A25 bulb: 25/8 = 3-1/8″ diameter

Most common base types:

Globe (G) bulbs have a full, round shape and are available in various sizes. They can be used for many applications throughout the home, such as foyer lights, kitchen lights, chandeliers, and ornamental fixtures. The most common type is the large G30 bulb, which is used in bathroom and makeup vanities.

Depending on the bulb, numbers in each code can refer to the bulb’s diameter in one-eighths of an inch or in millimeters.

G11 bulb: 11/8 = 1-3/8″ diameter

G14 bulb: 14/8 = 1-3/4″ diameter

G16/G50: 16/8 = 2″ diameter

G60: 60 millimeters = 2-3/8″ diameter

G25/G80: 80 millimeters = 3-9/64″ diameter

G30: 30/8 = 3-3/4″ diameter

Most common base types:

All of the bulbs in these groups resemble the shape of a candle flame and are often referred to as candle bulbs. Conical (C) bulbs are shaped like a cone. Conical angular (CA) bulbs are shaped like a cone but have a bent tip. Blunt-tip (B) bulbs are very similar to C-type bulbs but have more of a torpedo or bullet shape. These bulbs can be used in chandeliers, wall sconces, pendant lights, night lights, decorative light strands, holiday light strands, and other decorative home lighting applications.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

B10 bulb: 10/8 = 1-1/4″ diameter

CA10 bulb: 10/8 = 1-1/4″ diameter

C7 bulb: 7/8 = 7/8″ diameter

C9 bulb: 9/8 = 1-1/8″ diameter

C15 bulb: 15/8 = 1-7/8″ diameter

Most common base types:

BR stands for bulged reflector. Traditionally, the inside surface of an incandescent BR bulb is covered in reflector material that is used to gather and cast a wide beam of light away from the bulb. LED BR bulbs don’t require the reflector material. These bulbs can have a frosted, clear, or patterned dome-shaped lens that diffuses light and provides a gradual fade into nonilluminated areas. BR bulbs also produce less shadows when compared to PAR bulbs. They’re a bit longer than PAR bulbs and tend to protrude from light housings but are used in similar applications, such as track lights, recessed lights, display lights, or can lights.

BR20 bulbs are often referred to as R20 but have the same characteristics of other BR bulb types. The R stands for reflector.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

BR20/R20 bulb: 20/8 = 2-1/2″ diameter

BR30 bulb: 30/8 = 3-3/4″ diameter

BR40 bulb: 40/8 = 5″ diameter

Most common base type:

Multifaceted reflector (MR) bulbs are small in size with a reflective, faceted interior. The facets create a concentrated beam of light that can be displayed in a narrow spot or wide flood beam pattern. Because of the directional light they provide, MR LED bulbs don’t require the facets but often still have them. These bulbs are available in a variety of colors and can be used for many applications, including track lighting, recessed lighting, desk lights, and display case lighting. Many MR bulbs operate on low-voltage wiring systems, which makes them great for outdoor and landscape applications such as driveway lights, path lights, gazebo lights, paver lights, and malibu lights that have weatherproof housings.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

MR11 bulb: 11/8 = 1-3/8″ diameter

MR16 bulb: 16/8 = 2″ diameter

Most common base types:

Tubular (T) bulbs come in a variety of lengths and widths. Depending on their size, these bulbs can be used in applications ranging from chandeliers, wall sconces, and pendant lights to basement and garage troffer light fixtures.

Numbers in each code refer to the bulb’s diameter in one-eighths of an inch.

T7 bulb: 7/8 = 7/8″ diameter

T8 bulb: 8/8 = 1″ diameter

T10 bulb: 10/8 = 1-1/4″ diameter

T14 bulb: 14/8 = 1-3/4″ diameter

Most common base types:

Electrical transformers come in various sizes and shapes and there is a distinct possibility that you have seen one in the area your business is located in. The larger transformers are typically grouped together and are found in power plants and isolated and fenced-off areas.

While most people know that they shouldn’t get too close to these installations, most aren’t sure what the purpose of these transformers is and how they work. Here is some more information that will give you clarity about this.

These are essentially electrical devices that are used in transferring electricity from a higher voltage to a lower one and vice versa. Most of the electrical transformers are designed to serve the latter function. Without using too much of technical terminology, here is a short explanation of what they do – The process via which energy is transformed is called electromagnetic induction; this uses a magnetic field right through the process.

There are transformers of different types and they all serve different purposes, based on the scale of the project and output requirement. In household applications, they are used to power equipment and appliances as well as kid’s toys. The power that is generated from the large power plants is generally just too powerful for the application it is to be used in. This is where a transformer comes into the picture. It downsizes the electricity and turns it into the required voltage which then gets transferred via coils.

Apart from powering equipment and appliances in your home, electrical transformers also have a massive impact on our daily lives. Most homes and businesses aren’t situated close enough to a power plant. How then do these establishments and homes get the amount of energy they require to function correctly?

This is the point at which transformers come in use. The technology used to drive these transformers gives them the ability to transfer energy across long distances at quite an impressive speed.

Transformers are categorized in many different ways, based on their application, construction and purpose. The different types of transformers are:

Aside from these, the types of transformers used in residential and smaller commercial uses are:
