It is a common misconception that commercial and residential electrical systems are essentially the same thing. This is not true, however. A good Blackburn electrician knows that several factors differentiate the two principles – making them their own, unique fields of work. In today’s blog, we’re going to be exploring what those factors are and the different requirements and restrictions that each of the types of electrical works has.

Types of wiring

The type of wiring used in the two settings varies as the requirements are different. Residential wiring is typically quite thin but is protected by a sheath of plastic. This works to protect both the wire from any damage as well as the home’s occupants.

Because residential wiring runs through walls and ceilings it is constantly in contact with other surfaces. The sheathing protects the wire and also helps to avoid any fires from starting – especially since one of the surfaces the wiring will be in contact with is wood.

When a commercial electrical system is set up, the wire is generally much thicker. The initial coating of the wiring is also far superior to that of the wiring used in residential systems. This special coating is known as TTHT – which has a high heat resistance and is made of nylon and thermoplastic.

Another difference between residential and commercial wiring is that commercial wiring is always set up in conduit. If wire is set up in conduit, it means that a metal or plastic conduit pipe is used as a sheath to protect multiple wires. The primary purpose of conduit wiring is to add extra protection in case the wiring runs through exposed spaces.

Single and three-phase power

Single and three-phase power refers to the amount of electricity we have connected to our system. Single-phase – which is usually either 230 or 240 volts – is generally used for residential properties and small businesses that don’t expend much power. Single-phase power only has one fuse cartridge on your switchboard and will come into your property with an active and neutral wire – the latter of which is earthed at the switchboard.

Three-phase power is for larger electrical applications and generally used in commercial settings as the high volume of electrical traffic requires more power. Typically, either 400 or 415 volts, three-phase power has four wires running into the property – three active phases and one neutral, which is again earthed at the switchboard.

Three-phase power can also be used for residential purposes if you require a large amount of power. For example, if you do pottery as a hobby and have a kiln in your garage, then you’ll probably need the three-phase power to give you that extra boost.

Codes and standards

Several standards must be followed and met when working with and installing electrical systems. As the wiring and power output differs between residential and commercial buildings, so do the standards.

Commercial buildings have a lot stricter and rigorous standards as there is a lot more power flowing through the building – resulting in more safety precautions and checks that need to be done. Australian Standards such as AS/NZS 3000 dictate the relevant regulations and requirements when it comes to installing electrical wiring.
