Wollongong RCD safety switch services
An RCD, or residual current device, is a safety device that turns off an electrical circuit when it senses that the live and neutral currents are not equal. By turning off the power before something dangerous can happen, this stops electrocution and fires. Effective 2018, ALL circuits in homes must be protected by an RCD, which stands for "Residual Current Device" and is also known as a "safety switch." Hott Electrics can get you an RCD or safety switch and install it so that your home or business is up to code.


Shock protection
Things that help us live better and safer are made possible by technology that changes with the times. One piece of technology that has been made to keep us safe from electric shock is the RCD safety switch.
As the name suggests, an RCD is a safety switch that is meant to trip and break the circuit if the flow of current isn't balanced. Someone could get shocked if they touch a live wire or there is a problem with the wiring. RCDs are very important for home and office safety because they can stop electric shocks that could be very dangerous or even kill you.

Type A & type B RCDs
There are two types of RCDs: type A and type B. Type A RCDs are designed to protect against alternating current (AC), while type B RCDs protect against direct current (DC). Both types of RCDs are required by law to be fitted in all new homes and office buildings in Australia.
Prevent the flow of current
RCDs work by constantly monitoring the current flowing through the circuit. If there is an imbalance, the RCD will trip and break the circuit, preventing the flow of current. This can happen in as little as 0.03 seconds, which is fast enough to prevent serious injury or death from electric shock.
Test & inspect your safety switch
RCDs are a vital safety feature in any home or office, and should be regularly tested to ensure they are working correctly. If you have any concerns about your RCD, or would like to have one installed, or have your current switch inspected please contact Hott Electrics for an inspection.
