I have recently been asked to install overhead fixed ceiling track hoists in disabled peoples homes. The instructions that come with the regards to electrical safety are non existant, but the hoists have charger docks which are 240v on the primary side and on the secondary 26--28vdc. The charger then supplies 2x 5.5ah batteries. There is an earth wire on the supply cable but the charger is a class 2 item. I would like to hear other memebers take on the best method of installing these hoists.
