Why can’t I use a residential electrician instead of a commercial electrician?
Both are different specialisations that need to adhere to different standards. There are two primary areas where they differ.
Residential homes will use single phase power (240V). Commercial businesses will often use three phase design, offering maximum efficiency. This provides two legs at 240V and one leg at ~415V. .
Commercial wiring needs to be able to hold up to greater heat and pressure as well as corrosion. Certain commercial buildings will need to have backup generators in place.
If you use a residential electrician, you can be hit with a fine if the wiring is not done according to a commercial standard. There is no commercial standard per say The Electrical code AS3000 is across the board.
What are the licensing requirements for commercial electricians?
First things first: you need an electrical license to do any kind of wiring or installation in New South Wales. This applies regardless of whether it is commercial, residential, or industrial.
You also need a licence regardless of the total monetary value of the project. However, the type of license you need will depend on the overall monetary value. There is a $22,000 fine for doing unlicensed work as a sole practitioner and $110,000 for a company.
Can commercial electricians take care of air conditioning units?
Some operators offer air conditioning services, but this is only permissible provided they are licensed to do so. Electricians will need an ARCtick-approved NSW Fair Trading license to do the work. Otherwise, the only thing that can do is connect a single-phase AC unit to an outlet (which is basically nothing). You can’t install aircon units yourself as you will be dealing with potentially dangerous gases, and this will likely void the warranty. If anything goes wrong, you can’t make a claim.
How can I reduce my commercial electricity bill in Sydney?
The best way to do this is to first identify what you need. Only get three-phase power if your business really requires it since there are added fees. On the other hand, if you need the electricity there is little you can do. In the modern era, people want to remain connected and tools need electricity to operate.
A direct approach would be to upgrade your switchboard or do a rewire for the long term so that energy is properly distributed. You might also consider effective energy prices by powering down items that are not being used. Inefficient hot water systems (such as instant hot water) as well as portable AC units can be a major drain on electricity and are often unnecessary in a commercial context.
By installing efficient units on day one, you can reduce your energy bill for the long haul. The main ways for you to reduce your commercial electricity bill would involve:
- Improving building energy efficiency
- Using energy efficient equipment
- Getting annual maintenance
- Getting a high quality install
- Using alternative energy sources
- Seeking finance for energy efficiency improvements
What electrical safety features are required for commercial businesses?
A surge protector is useful for commercial enterprises because it protects sensitive equipment in the event of power surges. It’s especially useful if you own an IT business or hold significant amounts of sensitive data on servers (legal, medical, financial, etc). All modern fuse boxes will come with safety switches known as residual current devices (RCDs).
Apart from this, as long as your wiring, switchboard, and outlets are in line with regulatory standards and installed by a licensed commercial electrical services, you’re good to go. Just remember never to touch an exposed wire and to be mindful of the energy consumption of appliances.
