Top 5 signs your building might need electrical rewiring

Posted on under Installations, Services

Under the NSW Work Health and Safety Regulation 2017, any person conducting a business in a commercial or industrial property has an obligation to ensure the safety of employees, customers and any other person visiting the property. This means you need to be rigorous in maintaining the condition of your electrical wiring and respond immediately to any signs the building might need to be rewired. Here are the top 5 signs to look out for.

 

  1. Flickering or dimming lights
    While some flickering or dimming of lights is normal in situations where motor driven devices are being turned on (which pulls more amps from the circuit), they can also be a sign of an over-loaded circuit, faulty wiring or a faulty circuit breaker. If the lights in your industrial or commercial property are regularly dimming or flickering, you should have your wiring checked by a licensed electrician as soon as possible.
  2. Frequent blown fuses or tripped circuit breakers
    This is a significant sign that something is not right with your wiring, as it is an indication that your circuit is not handling the amount of electricity you need to run your business. It may very well be the case that your wiring is worn out and you need to rewire. If you are experiencing either of the above issues, your wiring needs urgent attention.
  3. Buzzing, charred or dead power outlets or switches
    All of the above are signs of something seriously wrong with either the switch or outlet in question, or with your wiring as a whole. As soon as you notice these warning signs, you need to contact an electrician and have the problem diagnosed and fixed. Failure to attend to these signs as soon as you notice them can potentially lead to a very dangerous situation.
  4. Electric shocks from power outlets or switches
    As above, if your outlets or switches are giving a shock when used, this is a sure sign things are not right with either the outlet or switch, or with your wiring. If you or any of your employees receive a shock from an outlet or switch, you must get an electrician to find out what’s going on as a matter of urgency.
  5. Cracked, cut or broken insulation cable
    Insulation cable prevents your wiring from coming into contact with other conductors, protects it from the elements and inhibits electrical leakage. For this reason, it is essential that the cable is in good condition throughout your entire electrical circuitry. To prevent more serious electrical issues, ask your electrician to carry out an inspection of your wiring and replace any damaged cable. If the damage is extensive, you may need to rewire the building.

 

While there are a number of other signs that point to faulty wiring, the above are the most common indicators and should never be taken lightly. Always ensure that the electrician diagnosing and fixing the issue is licensed and has experience in the relevant commercial or industrial context.

 

Under the Workplace Health & Safety Regulations, all businesses must maintain a regular Test Tagging schedule, to avoid damage to people or property from electrical equipment or circuitry.
At Caslec, our highly experienced commercial and industrial electricians provide Test Tagging services to businesses throughout the Greater Sydney region. Call us today on 1300 659 273 to discuss or visit our Service Areas page to find an electrician near you.

How to become a licensed commercial or industrial electrician

Posted on under General News

With skilled electricians very much in demand across all industries, pursuing a career in the trade offers scope for variety and progression, good remuneration and the opportunity to specialise in a range of areas. Below we set out the most straightforward pathway to becoming a commercial or industrial electrician, specifically referring to gaining your license in NSW.

Working as an electrician requires a high level of technical and mathematical skills alongside physical fitness and good eyesight (e.g. you cannot be colour blind as you need to be able to distinguish between colour coded wires). It is a job that demands a keen attention to detail and safety procedures and the ability to manage risk. You also need to be able to read and interpret complex electrical diagrams.

While there are a number of pathways to becoming a licensed electrician, according to the NSW Department of Fair Trading the most direct route is as follows:

  1. Completion of Certificate III in Electrotechnology Electrician AND all of the following:
  2. A Certificate of Proficiency as an Electrician or an Electrical Mechanic from the Department of Education and Communities (DEC) or the Vocational Training Tribunal (VTT).
  3. At least 12 months relevant electrical wiring work experience* utilising knowledge and understanding of the AS/NZS 3000:2007 in the residential, commercial and/or industrial areas required by NSW Fair Trading ‘Referee’s Statement Electrical Work’ form current at the date of the application.

    *‘Experience’ means experience that is lawfully gained by the applicant (whether during or after completion of an apprenticeship) as a bona fide employee who has been paid during the relevant period of employment in accordance with an award or enterprise agreement.

Once you have been attained your electrician’s license, going on to specialise in commercial or industrial electrotechnology often means a combination of on-site training and further study.

Firstly, look for a role with a Level 2 Accredited Service Provider (ASP) that specialises in commercial and industrial services, giving you the opportunity to gain hands-on experience in the field. Working alongside electricians who are highly skilled in the industrial and/or commercial sector is the best way to learn what’s required in the role and to discover where your strengths and interests lie.

You may also want to consider further study while you’re working, in order to enhance your skills in a particular area, such as photovoltaic systems, electrical machine repair or data & communications, to name just a few of the specialisations on offer.

Although becoming an electrician takes some time and commitment, it is one of the most secure trades on offer and is only going to become more crucial as electrical systems evolve. If you’re interested in applying for an apprenticeship or a role at Caslec, visit our Careers page.

The 6 types of fire extinguisher & when to use them

Posted on under Tips

All Australian workplaces must comply with the fire safety standards set out in the Work Health and Safety Regulation 2011, with many states having their own additional regulations around fire safety and emergency training. Yet, according to research, only 13% of people know what class of extinguisher to use on what kind of fire.

In the following we set out the 6 basic types of extinguisher installed in industrial and commercial premises in Australia and the class of fire they can be used on. It is important to understand that using the wrong type of extinguisher on a fire can be highly dangerous.

Class A extinguishers are used on fires that involve paper, fabrics and textiles, wood-based products, plastics and rubber-based products.

Class B extinguishers are used on fires that started as a result of flammable or combustible liquids, such as chemical-based cleaning products, electrical contact cleaner and lubricants.

Class C extinguishers are used on fires started by flammable gases and can potentially extinguish the fire before pressure builds.

Class D extinguishers are used for fires started by combustible metals, such as sodium, potassium, uranium, lithium, plutonium and calcium, and are often used in laboratories. The most common Class D fires involve magnesium and titanium.

Class E extinguishers are used to stop fires in electrically energised equipment, including fires in equipment that requires electricity or a circuit to operate.

Class F extinguishers (fire blankets) help to control fires caused by cooking oils and fat-based products, such as could occur in a commercial kitchen.

To meet Australian Standards and workplace OH&S regulations, you must have the correct portable extinguishers installed in your workplace and personnel who are trained in their use. This training must be refreshed every two years.

One way to protect your business and employees against the risk of electrical fire is to ensure you adhere to a regular test-tagging schedule, where the safety of any electrical equipment is assessed by qualified electricians. If you work in a ‘high-risk operating environment’, such as a kitchen, warehouse or factory, you need to have your equipment test-tagged every 12 months.
