Electricity may either be connected by 230 or 240 volts (these are called single phase circuits that are installed in most residential applications), or 400 & 415 Volts (3-phase). The latter are typically best-suited to provide power to heavy-duty appliances and equipment and in industrial settings as well as larger commercial applications.

Some people have electric kilns installed in their homes or garages because they indulge in making pottery or ceramics products. Certain homes have very elaborate and large, ducted air-conditioning systems. In all these situations, a 3-phase circuit would be required to support this heavy power usage.

The type of circuit used is dependent in the equipment or appliances installed on your property. It is important that you check the power & voltage requirements of the installations properly, before deciding what type of circuits you need. In most instances, even massive ovens and high energy-consuming heaters are typically singe-phase.

This current in amps has to be multiplied by the voltage to give you the power in watts. If a 3-phase supply is available, the total voltage of 24,000 watts will be divided by 3; this means 8000 watts will be used in each phase. This means the current in each phase is lower than 1/3rd of what it generally is in a single phase power supply (about 30 amps in each phase instead of 100).

The aspect to keep in view here is that if you have a 3-phase electrical connection, you will end up paying higher connection fees for it. In addition, you would have to pay fixed annual charges for 3-phase as well, so you shouldn’t be considering it for your new home unless it’s really needed.

Depending on the locality you live in, your property may also be connected to a SWER electrical line and many country areas have them. The SWER (single wire, earth return) delivers single-phase power. It is a very economical way of power distribution since it requires only a single transmission or active line. The earth is used as the return conductor and there is no neutral line.

In case you need to use any 3-phase motors in these settings, you would have to get a single-phase to 3-phase converter installed. Choosing the right phase is crucial to the optimal working of your equipment and for the safety of your property as well.

Lighting fixtures can be a great addition to your household especially if you’re looking to improve your home’s appeal. Dim or flickering lights can be frustrating to deal with and can cause a real headache. Turning the lights on to only find yourself surprised with weak light bulbs can be inconvenient. And when it comes to your kitchen and bathroom, lighting fixtures are so beneficial since they see the most usage in your home. With poor lighting efficiency, you will see a decline in functionality for either room. Lighting is always going to be a key component for your home and that is why it is important to take care of lighting issues. When you’re looking make upgrades for your home, lighting fixtures should be at the top of the list.

Track lighting is a great option for homeowners who are looking to increase both the appeal and visibility of their bathroom or kitchen. Since track lighting is fairly easy to install, it can become an immediate update to increase the degree of illumination for your home. Track lighting will also allow you to point lamps in any direction, increasing the level of customization of lighting fixtures that you can take advantage of.

One of the lesser lit areas of your bathroom or kitchen is probably around your cabinets. It can be frustrating trying to find spices or even towels without enough lighting surrounding it. A helpful lighting installation is adding one under the cabinets. This is the best solution to this problem and in the meantime, adds an ambiance to the kitchen and bathroom areas of your home.

Feeling classy? Finding unrivaled lighting fixture.

The term “arc flash” is used to describe low impedance connections in an electrical system, which allows movement of unwanted electric discharge through the air from one voltage phase to another, or to ground. This leads to a rapid rise in temperature and pressure in the air between electrical conductors, causing an explosion known as an arc blast.

Arc blasts and the resulting heat can lead to fires, pressure waves and flying shrapnel that result in serious damage to life and property. These explosions typically occur without any warning, destroy electrical equipment completely and lead to severe injury or death of personnel present within the boundary of the arc flash.

What Are the Main Causes of Arc Flash?

Arc flash occurs when several electrical conductors are placed close to each other, with significant fault currents flowing through them. In this situation, ionization of the air can take place as a result of various factors – such as differences in potential – which leads to a low resistance path and allows current to flow through the air gap between conductors.

Many people assume that low voltage equipment is safe from arc flash, but arc flash hazard levels may be higher at low voltages, due to the high fault currents. Most incidents that occur in low voltage systems are caused by human error, e.g. a tool slipping while a technician works on electrical equipment.

Arc flash can also be caused due to:
