As with any type of home repair service, the cost of a project or repair will vary depending on what type of work you need to have done. If you have an electrical repair, for example, the electrician will need to take out his tools and do some electrical troubleshooting in order to determine exactly what and where the problem is. If this is the case, it’s not possible to give an exact electrical estimate before starting, and the job will need to be done on a time an material basis. The electrician should give you an accurate quote of their hourly rates, and the cost of materials that they charge you for should be realistic. If the electrician is knowledgeable and competent and the repair is straight forward, they can usually fix the issue within a fairly short amount of time and at a reasonable cost.

If you need a panel upgrade, new lighting, smoke detectors or any other type of electrical installation, you’ll want to make sure that you know the exact price before the job is started. For your own protection, this is very important.

Electric Connection, a licensed Pasadena electrician, can give you a ballpark price over the phone for most types of electrical installations, and then schedule an appointment to go out to your house or business property to give you a detailed price in writing. Getting a price in writing for the work you need done means no surprises for you at the end of the job and less stress for you while the job is in progress, too.

If you need an electrical update or installation, you can call our office and let us know exactly what you’re looking for, and we’ll be able to give a ballpark figure and some free electrical advice. If you like the ballpark price, we can schedule an appointment to go out to your property and give you an exact electrical estimate in writing. We’re a licensed and bonded electrician Pasadena area residents can depend on. You can also visit our website at www.theelectricconnection.com/electrician-pasadena-ca to find out more.

You’re on top of grounding your children, but are you familiar with grounding your home? It improves the safety of your home as well as increases the life of your electronics, and who doesn’t want that? Mr. Electric has all you need to know in order to have your home properly grounded.

Electricity likes to travel the path of least resistance. When there’s too much of it, it needs somewhere to go. That’s where grounding comes in. You see, without it, that path of least resistance is your appliances and electronics – and possibly you when you use them. Burn! Zap! Not a good thing.

Since you don’t want your appliances – or you – to take the heat in these situations, a grounding wire is added to your home, offering all that electricity the perfect chance of escape, via a wire attached to your home’s electrical system which is submerged firmly in the ground – the reason it’s called “grounding.” Both your home’s electrical box and your home’s outlets need to be connected to this grounding wire in order to be properly and safely grounded.

Without proper grounding, you and your home could suffer burned out electronics and appliances, electrical fires and potentially deadly electrical shock.

Without special testing equipment, it may be difficult to tell. Just because you have three prong outlets does not mean the outlets – or your home – are properly grounded. These outlets must be properly wired in to your home’s main grounding wire for proper protection. There is also more to grounding than sticking a big metal rod in the dirt, such as properly attaching wires, grounding to your home’s water pipes correctly, and much, much more. If you don’t want your electrical behaving badly, you can ensure it is properly grounded by having it inspected by a licensed, qualified electrician.

Newer homes, as a result of increased safety regulations, are typically properly grounded. Older homes, on the other hand, may not have had a proper grounding experience, or any at all. Homes built before 1950 are especially at risk. You should always have your home, regardless of age, inspected for proper grounding by a licensed, qualified electrician to avoid the potential risks of fire, electrical shock, and property damage. You never know what the previous resident did without a permit.

Don’t suffer the punishment of burnt out electronics or a burned down home. Mr. Electric® will keep you out of trouble – get grounded today!

Programmable logic controllers provide automatic control of processes so that very little human intervention is required. Yet, this results in a well-coordinated, repetitive process.

These systems automatically start and shut down critical equipment in large and complex manufacturing processes. When in operation, programmable logic controllers ensure that all conditions are met before starting up a certain machine or process. In addition, the PLC continues monitoring the entire system using a variety of sensors.

Consequently, this ensures that everything runs as programmed. The PLC will trip if it detects a malfunction or abnormality in any of the monitored parameters.

The operating environment, size of the processes, ease of access by operators and maintenance personnel influence the choice of PLC.

A harsh environment with dust or small particles will require a PLC system with an appropriately IP rated enclosure. This prevents ingress of foreign particles into the system. The available space and layout also influence the choice. Therefore, most users require easy access for reprogramming, maintenance, or troubleshooting.

The simplest form of a PLC, all the basic components of a PLC include the I/O points, CPU, and software program. It is typically housed in a single enclosure. These PLCs are attached directly to the equipment being controlled.

Modular PLCs consists of several components on a common bus within a base unit to allow extending of the input and output. These units work on an expandable base unit. Therefore, it provides all the basic components of a PLC, i.e., a power supply, I/O points, memory and the CPU, and slots for additional cards.  These modules, which may be from the same or different manufacturers, are plugged together into a base unit.

This follows the same modular concept, but each of the modules plugs into a rack. The add-on modules are contained in racks which are then linked together through a network of connections. Since the rack mounting PLC is highly scalable, it allows very large systems to be assembled.

In energy management, the PLC monitors and controls equipment such as boiler systems. It helps the organization increase energy efficiency and safety. PLCs are also used in numerous everyday activities. They are found in factories, homes, commercial buildings, airports, unmanned car parks, and more.

Finally, some practical applications include:
