To celebrate the festive season, PEW will be showcasing our very own 12 days of christmas. Across 12 days, we will be bringing you the latest products from six manufacturers and point of sales from six wholesalers.
Further amendments to the safety standards BS7288-2016 went live at the end of November 2019 and GreenBrook has ensured its PowerBreaker RCD products adhere to the latest regulations. The new standard requires Type A RCDs and Type AC RCDs. Type A RCDs can detect pulsating DC currents and surge faults that Type AC RCDs may not detect.
Pulsating DC currents are created from faults in modern electronic equipment such as EV car chargers, solar panels, multi-media equipment, USB sockets, i-phone chargers, SONOS, Alexa and more. This new standard requires much more rigorous testing of the RCDs with high voltage and short circuit tests. Products that adhere to this standard have a more sensitive/stable trip window so are a much safer defence against electrocution.
Another visible change to this standard is the additional markings on the front plate and the mechanical coloured flag indicators; which must now be green and red. To keep with its stylishly designed front plate; these indicators are placed within the window. A RED flag shows the device is ON with a live supply to the appliance. A GREEN flag shows the device is safe with the supply to the appliance switched OFF.
GreenBrook is part of the BEAMA Technical Committee who helped to write the revised standard.
