What is an RCD & Why Does It Need Testing?
Life-Saving Protection
An RCD is a safety device that switches off electricity automatically if there is a fault. It can save your life by preventing electric shock and electrocution — cutting power in as little as 30 milliseconds.
Millisecond Response
RCDs constantly monitor the electric current flowing through circuits. If a fault is detected, they cut the power faster than a heartbeat — before a lethal shock can occur.
Required by Regulations
Current BS 7671 regulations require RCD protection on most circuits in domestic properties. All socket outlets and bathroom circuits must be RCD protected in Sussex homes.
Regular Testing Essential
RCDs can fail or become less effective over time. Regular professional testing ensures they will work when needed most — in an emergency.
