Double Insulated Bathroom Lighting
If your lighting circuit does not have an adequate earth you can either have your wiring upgraded to incorporate an earth or use lighting that is double insulated.
Double-insulated lighting, also known as Class II lighting, is designed for enhanced safety, particularly in situations where an electrical ground (earth) connection may be lacking or unreliable. Scroll down for more information on double insulated lighting and reasons why you might need to use double-insulated lighting:
When considering lighting for areas with increased moisture or in locations where grounding might be uncertain, opting for double-insulated fixtures is a prudent choice to prioritize safety. But always follow local electrical standards and regulations to ensure that your lighting installations meet the necessary safety standards.
Double Insulated Bathroom Lighting - Class 2
Double insulated Class 2 electrical equipment has all exposed metalwork separated from the conductors by at least two layers of insulation, so that the metalwork cannot become live. There is no earth connection in the lighting and often manufacturers specify that no earth shall connect to the fitting. Your safety depends upon the integrity of the two layers of insulation. British double insulated equipment is marked with the double insulated logo (one square inside another), states “DOUBLE INSULATED” or Class II.
So, why would you require double insulated lighting? Here are the four reasons why you, or your electrician, requires double insulated lighting:
- You have no earth present in your lighting circuit
- The earth present on your circuit is inadequate or insufficient
- Your electrician cannot cross bond between your lighting and other electrical items in the bathroom.
- Your electrician cannot route an earth cable directly to your lighting because of existing decoration or tiling.
