New installations must be properly set up and comply with present regulations. Additionally, electrical installations can degrade with age. This is because of several aspects; for example, corrosion, wear and tear and harm. Due to this wear and tear electrical testing and examination is required.

Most of the installations in domestic properties have had some wiring alterations at some time. From experience, we have found that the majority of these modifications to have been faulty. They may have been wired incorrectly or do not conform to the guidelines. There are also highly dangerous methods carried out in the installation.

Types Of Electrical Testing

The right tests need to be executed for your Class I or Class II appliance in this order:

  • Visual Inspection
  • Insulation Resistance Test
  • Further tests are applied for leads, RCDs etc
  • Earth Continuity Test
  • Leakage Test

Class I Equipment

Safety Class I electrical equipment is electrical devices that rely on the Protective Earth. This is the solitary insulation for its safety and security. These usually have rather a lot of revealed steel and are typically heavy. Some examples of Class I equipment could be:

  • Dishwashers 
  • Irons
  • Electrical Machinery
  • Saw Benches
  • Washing Machines
  • Fridges
  • Drill Presses
  • Bench Mill

Class II Equipment

Security Class II electrical tools rely on two layers of insulation. These are sometimes strengthened insulation which will replace both layers of insulation. However, the strengthened insulation will be equivalent to the two layers of insulation.

This kind of appliance is often referred to as a 'dual shielded' device. It will typically be shown with the double box symbol.
