RCD vs PRCD: Why are they needed?

A portable RCD is an essential part of any testers kit for any test & tag job. But what are they and why are they so vital for testing and tagging electrical devices. More importantly, how do portable RCD differ from a regular RCD?

What is a RCD?

A Residual Current Device is used to prevent electrical shocks or electrical fires. By measuring the current in a system it can detect whether the electricity is flowing through an unintended path and automatically shut off the circuit. For example if electricity enters a person the residual Current Device will cut the power before it can give you too nasty a shock. Potentially saving a life or preventing an electrical fire.

Typically you can find RCDs throughout your home in places such as in the fuse box. They may also be built into socket outlets and some extension cords.

What is a PRCD?

A portable RCD is an especially useful piece of kit for any electrician or tester. By having a PRCD the user can guarantee their safety when working with an appliance that is of safety concern. It can plug into any standard socket and automatically cut the power when it detects any issues.

In fact, portable RCDs are so important they are often built into portable appliance testers

Whether you are a professional or planning on doing any DIY involving appliances, an RCD is a must have. Metrotest has a selection of reliable RCDs to choose from. Visit our store or get in contact with us to find the right portable RCD for you.

Here are 3 Reasons to Hire Quality Testing and Tagging Specialists

Testing and tagging is the process of checking the safety of portable appliances. Testing and tagging involves a visual inspection followed by electrical testing with a Portable Appliance Tester. The tagging refers to the labels attached to tested appliances to indicated their safety. 

Although testing and tagging is somewhat straightforward, the implications of an improperly performed test could result in serious injury. So, hiring a quality testing and tagging specialist, with attention to detail is vital to reduce risk. To test and tag, one needs to be deemed competent under the current standards and does not necessarily need to be an electrician. Appliances need to be test regularly to reduce risk, and poor testers may miss or ignore the signs of danger.

Competency

A competent test and tag specialist ensures the standard and best practices are followed. The standards only outline how to safely and correctly test an appliance. Whereas, the best practice goes above and beyond these outlines to ensure a comprehensive service. A competent tester tests patiently and tags accurately. The tester will then keep a detailed record of every test with numerical data.

A less quality testing and tagging specialist may rush through their tests, and in the process follow the standards incorrectly, putting themselves and you at risk.

Quality Testing and Tagging Guarantee

As stated, a quality tester will keep detailed records of their tests. Under the standard record keeping is not required. However, even the most basic record keeping is strongly recommended. The ability to look at the exact results of a test gives you a guarantee that the test has been performed correctly, and its results are certain.

Simple pass/fail records can easily be made up, and if the tester was to be audited, little could be done to hold them accountable for dodgy testing and tagging.

Professionalism

We have heard many horror stories of testing and tagging specialists who rush through their tests and have little regard for the environments they are testing. At Metrotest we take pride in our brand image, and the quality service we provide.

Part of that means keeping a professional attitude and complying with the health and safety protocol of the workshops we frequently test. After all, testing and tagging is about preventing injury, not potentially causing one.

Here is what one of our recent clients had to say:

“I would like to express my thanks to you and your team for their professionalism, punctuality, attention to detail and the general way they conducted their work on site. The guys were always polite and worked around my office and workshop teams, to ensure they did not interrupt business, whilst adhering to our site health and safety rules.

A team to be proud of!” – Haydn Murray, ETEL South Island Business Manager

Hopefully, you learned what to look for in a quality testing and tagging specialist. If you need your appliances tested, give Metrotest a call at 0800 638 768 or contact us online for more information.

If You Don’t Test and Tag, You Take a Risk

Test_and_tag

Not everyone sees the importance to test and tag their appliances or other electric-powered equipment. This is most especially true when a piece of electrical equipment is relatively new. Unfortunately, this poses risks to everyone who gets access to an electric-powered tool or appliance. However, we believe that it’s crucial to perform regular appliance testing and tagging, no matter how old or new an item is.

After all, no one wants to experience electric shock or other potential mishaps with a faulty appliance. To give you a more precise grasp on the importance of testing and tagging, here are the usual risks that come with a defective piece of electrical equipment.

Test_and_tag

#1. Increased risk for electrical shock

If you work in a cramped space and your appliance or equipment develops an electrical fault, it becomes difficult to avoid or prevent electrical shock. Unfortunately, an electrical shock can cause the following effects on the body:

  • Muscle spasms
  • Cardiac arrest
  • Nervous system malfunction
  • Burns
  • Increased risk for developing eye cataract

#2. Faulty appliances can cause damages

Without conducting regular testing and tagging, some of your electrical equipment becomes increasingly vulnerable to damage. It can also cause damages to your property. Below are some examples of potential problems that you might have to deal with if you have faulty equipment:

Fire_test_and_tag

  • Fire damage – Fire damages are perhaps the most dangerous outcome of having a defective piece of electrical equipment. The electrical short spark can cause the appliance to go up in flames. It can also affect flammable materials inside the property like wallpaper, insulation, cabinetry, and curtains.
  • Physical damage – When an appliance starts acting up, it can cause physical damage to itself, the outlets, switches, and other components of your electrical system.
  • Damage to the surge protector – Each electrical equipment comes with microprocessors that detect power surges (electrical supply fluctuations, lightning storms, etc.). Unfortunately, if you don’t get your appliance tested and tagged, you may not be aware of potential problems resulting in damage to your surge protectors. This could potentially decrease its lifespan because it has less protection from power surges.

#3. Increased difficulty in managing risks in workplaces and homes

When you’re not sure about the integrity or safety of an appliance or a piece of electrical equipment, you become increasingly wary of the risks involved. This makes it hard to work around the devices. It also adds to your responsibilities and duties.
