As technology moves forward, our knowledge of electricity and our ability to make it safer for us to use has also advanced. One of the latest and greatest things we have at our fingertips is GFI outlets. You have probably seen these in some buildings and maybe even a few new homes. The National Electric Code has made these outlets a standard. Kitchens, bathrooms and other areas that are near water like pools and spas are all required to have GFI outlets in place instead of the standard outlets. If you are not sure if you have one of these, call The Electric Connection and we would be happy to explain. You can also read on and learn a little more about what they are.

Your electrician in Pasadena will explain exactly what GFI outlets are. These outlets look different than the standard ones you have seen for decades. There are 2 buttons in the center of the outlet. 1 red and 1 black. These are to test whether the outlet is working and the other is to reset it.

GFI or Ground Fault Circuit Interrupters can prevent against electrocution in the event a person is standing or touching water while using an electrical appliance. The GFI detects the very millisecond the electricity is no longer flowing along its proper second. As soon as it detects the break, it cuts power to the appliance, thus preventing a terrible accident. This is where the reset button comes into play. Simply reset the outlet after the situation has been made safe.

This is a fairly simple precaution you can take today to prevent a serious, life-threatening accident in the future. If you would like to learn more about replacing your existing outlets with GFIs, call an electrician. Pasadena residents can rely on The Electric Connection.

A Programmable Logic Controller (PLC) receives information from one or more inputs. This semiconductor control device processes the information based on a software program. Finally, it sends an output control signal. The microprocessor based control system performs functions such as timing, logic, sequencing and others. The PLC follows instructions from an operator-defined program.

These intelligent systems provide reliable, high-speed monitoring and control of processes in automated applications. In addition, they are easy to program and configure.

Once the program updates the output, the CPU starts over and the cycle repeats again. The cycle depends on the number of inputs, outputs, and size of the program, while the action will depend on the inputs coming from a variety of sensors.

The input sensors include components such as switches, proximity sensors, photoelectric sensors, pressure switches, level switches, encoders and temperature sensors, while the output devices include actuators, relays, switches, and many more.

PLCs rely on software programs that help them in making the necessary decisions. The PLCs are programmed through a variety of tools, which may differ in ease of use, appearance, and complexity. The most commonly used PLC programming language is Ladder Logic, a graphical software that uses common electrical symbols. Other languages include Function Block Diagram (FBD), Sequential Function Chart (SFC) and Structured Text (ST).

The programming is done on the device such as a computer or handheld device after which it is transferred to the PLC memory using a communication interface.

Selecting a suitable PLC that will address your current and future needs can be a challenge, especially with the large number of different PLCs on the market today. The available PLCs have varying capabilities, physical sizes, complexity, cost, power requirements, scalability and other parameters. Therefore, it is necessary to determine the correct programmable logic controller for your specific application. Special systems can be designed for use in harsh environments.

The Programmable Logic Controller has revolutionized and simplified controls in automation and industrial applications. PLCs are easy to install, wire, program and modify to suit changing application requirements. These control systems are usually available in a wide range of sizes that ensure finding exactly what you need for any application.

The type of in-wall wiring and cables you choose for your home will largely depend on what kind of signal you need to carry, where you’re going to route the wire, and how far the signal will have to travel between your various peripherals. Whatever type of wiring you choose to go with, you want to be sure you get one that’s rated for in-wall use by the Underwriters Laboratory (UL). This is usually going to be indicated with a CL2 or CL3 rating when it comes to speaker wire and audio/video cables. A good number of Ethernet cables are rated for in-wall use as well, usually indicated with a CM, CMR, or CMP rating. When choosing the right rating for each specific type of wiring, the UL looks at a range of different factors, including the heat being generated from current flowing through the wire, how quickly the cable will catch and spread fire when exposed to flame, and the wire’s vulnerability to damage from external stresses.

It is also important to look for a cable that’s rated for your specific needs. For instance, you are going to want cable that is rated as CL2P or CL3P if you are planning to run it in your heating ducts, or if you are looking to run your cable underground to connect to your outdoor speakers, you will want to make sure your cable is rated for direct burial. It should also be noted that when you are making the decision of what custom wiring you will need for your home, you need to be aware of your local fire codes and make your selections accordingly.

When you are looking for the right type of speaker wire for your home, there are two things you need to factor into your decision: the gauge and number of conductors. The gauge of wiring you choose should depend on how far the wire is going to have to travel from the receiver to the speaker. Significant power loss can occur over long runs of wiring, reducing your system’s performance. This might not be a significant issue in a single-room setup, but it is something to keep in mind if you are looking at a multi-room system. In terms of conductors, speaker cable comes with two or four. Two should be all you need for wiring a single speaker, but if you are looking at doing a multi-room setup, or a system with volume controls, you will mostly likely want four.

No home wiring setup would be complete without a solid Ethernet setup, but knowing which type of wiring to use can be a little confusing. When you are looking to create a wired computer network in your home, or carrying audio/video and control signals all across the home, CAT-5 cables have been the standard for a long time, but a better option these days might be to look at CAT-5e or CAT-6 cables. These newer cables are able to pass more data along the wire at a much faster rate than the older wires. The CAT-5e and CAT-6 wiring options are also backwards compatible with devices that were designed to work with the older CAT-5 wiring, meaning you won’t have to buy all new equipment. Ethernet cabling actually stands up to interference better than almost all audio/visual cables, which is a large reason it has become so popular in recent years for whole-house audio/video systems. It can also be a more cost-effective option to run long lengths of Ethernet cabling than it can be to run the same length in audio/video cable.
