Charging lockers feature a safety overload switch that shuts off the circuit if too many devices are attempting to be charged at once. The electrical components are sourced from premium companies such as CMS Electracom and Elsafe Australia. Their products all strictly comply with Australian and New Zealand safety standards: AS/NZS61535. 1:2003 and AS/NZS 3112 : 2011. The parts are supplied to us in segments that plug and play - no electrician is required in house. The only time an electrician is requires is if you opt for a hardwired solution.
