Electrical Switches Installation And Sockets

Tips for Installing Electrical Boxes

Installing electrical boxes is one of the first stages in electrical rough-in work. It is regarded as very easy work—more like carpentry than electrical wiring—but there still some common errors that DIYers frequently make. Follow these easy tips to make sure your electrical box installations look professional and meet code requirements.

Install Wall Boxes at Uniform Heights

It surprises some novice DIYers to learn that there are no precise code guidelines for how high wall switches or outlet boxes should be positioned. But professionals follow certain standards for a uniform look.

It’s standard practice for wall switches to be installed about 48 inches above the floor, but this distance can range from 43 to 53 inches, depending on your preference. For spaces used by people with accessibility issues requiring a wheelchair, for example, lower switch heights might be practical.

Common practice for receptacle outlet boxes is to install them so the bottom edge is between 12 and 16 inches above the floor. This distance, too, can be adjusted for special circumstances.

For switches and outlets above countertops, install them so the bottoms are about 4 inches above the countertop surface.

The Complete Guide to Flow Switches

What is a Flow Switch?

A flow switch, sometimes referred to as a flow sensor or flow indicator, is a device used to monitor the flow rate and pressure of liquids, air or other gaseous media through a duct, system or loop. These switches or sensors can be used to monitor flow over a given period of time, or set up to continuously monitor total flow. Technically, a flow meter or indicator may not necessarily be a true flow ‘switch’ – if the device only registers and displays information, it’s more properly called a meter or indicator.

How does a Flow Switch work?

To understand how a flow switch works and what it does, it’s helpful to outline the core components that make up a typical switch or sensor of this kind. Many types will include a paddle or magnetic trigger of some sort (the primary device), which is connected to a circuit and placed in the channel through which liquid or gas is passing. This paddle is displaced or rotated by whatever substance is flowing by, and sends a signal reading back to a secondary component known as the transducer.

The transducer takes this raw signal from the paddle and passes it on to a transmitter in a readable format. The transmitter, in turn, measures this reading against a predefined set of parameters and performs whatever signal or action is required to adjust the behaviour of components and mechanisms elsewhere.

How to install and test a Flow Switch

Because there are so many different kinds of flow switch, as we’ll see in subsequent sections, there’s also a very wide range of flow switch installation methods and techniques. When looking for information on how to wire a flow switch, most important thing is to have a clear understanding of which type of switch you’re using and for what purpose.

Different types of Flow Switches

There are numerous different types of flow switches available, and each will take a subtly – but importantly – different approach to measuring linear, nonlinear, volumetric or mass flow rate of liquids or gasses. Before ordering or installing a flow switch, it’s extremely important to have a clear understanding of which specific type you need for the exact application you have in mind.

 

Cost to Install a Light Switch

The cost to install a light switch is affordable at an average of around $145. Most homeowners pay between $98 and $194 for the service. Transfer switches can be purchased and installed in a range from $300 to $2,400, depending on the model. Adding dimmers averages $100 to $200

If you’re thinking about installing new light switches in your home, the first thing you need to do is find a licensed electrician. The same is true of dimmer and transfer styles because properly wiring these products is vital to safety and efficiency. Licensed professionals are well-versed in local codes and laws.

Qualified electricians can make sure that everything is up to code, which means that you’ll pass home inspections and rest easy. Though the process seems simple and the expense of hiring an electrical professional could seem unnecessary, even the most basic electrical tasks are complex and dangerous, so it’s best to stick with the pros

Transfer Switch Installation Costs

Professional installation of a transfer switch averages $200 to $400 because electricians charge $50 to $100 per hour, and this is a 3 to 4-hour job. The units themselves are priced in a range from $100 to $800 for a manual and $300 to $2,000 for an automatic. These price ranges are associated with residential use. Commercial-use units are much more expensive.

Transfer switches are installed near the main breaker of your home and direct power from a portable or standby generator to select appliances. They change the power source from the main panel to the generator and prevent power from reversing into the local utilities. Such a reversal, or “back feed”, would be hazardous to the electricians working to repair local utilities.

 

Choosing and installing security lights

Security lights are a practical and attractive way to banish the shadows from the approach to your property. We look at outdoor lighting, the best place to install it and how it can help provide extra security.

Outdoor security lights can make your life easier when looking for your keys, and provide reassurance when you approach your property at night. A Which? Trusted Traders survey found that 70% of people worry about home security during the darker winter months, once the clocks go back. A quarter will leave lights on inside the house, to try to show it is occupied.

Security lights can really help to brighten up the area around your home. At the back of your property, external lighting can bridge the gap between indoors and out. This opens up the space for socialising, as well as allowing you to monitor activity in your back garden.

Security lighting should be installed by an experienced electrician who can plan where it will be most effective outside your home. Poorly located lighting can create glare, which actually reduces visibility.

Where to install security lights

recommends installing security lights above and to the side of your front door, to give you clear sight of callers. Ensure the light is not too high up or straight above the door, as that can put any caller’s face in shadow, making them more difficult to identify.
