A residual current device or RCD is a safety device that is designed to automatically switch off electricity in case of faults. These switches are significantly sensitive than your normal circuit breakers. Additionally, they offer protection against electric shock. This is why if you don’t have RCDs installed yet, you need to think of getting them now.
RCDs monitors the flow of electricity in your home. When it detects abnormality in the flow, it will automatically switch off the circuits, so serious injuries are avoided. It is important to have this additional protection. Otherwise, a simple job like mowing the lawn can result into serious disasters.
There are different types of RCDs: Meter Box Mounted RCDs, Combination RCD and circuit breakers, Portable RCDs and Power Point RCDs.
 |
Meter Box Mounted RCDsThe law requires that RCDs be fitted to the home’s power circuits. Generally, this type of RCD is located alongside the circuit breakers. You need two of these to ensure light remains if one of your RCDs operates. |
 |
Combination RCD and circuit breakersThese devices combine RCDs and circuit breakers. They protect your home’s appliances and electrical circuits. They also prevent electrocution. These are a good option when you need to do retro-fitting and there is little space available. |
 |
Portable RCDsThese devices are attached to the power board. Unfortunately, they only protect circuit appliances that are attached to them. However, they are perfect for people using power tools that are not protected by the meter box or power point RCDs. |
 |
Power Point RCDsThese devices are fitted to your home’s first power point right after the meter box. They are perfect for protecting electrical appliances in specific areas of your home. |
Your family’s safety is very important. We strongly recommend that you use a registered electrician to install RCDs in your home. For more information and tips about RCDs, check out this video:
