We were asked to replace the existing pendant lighting and install maintained emergency lighting. What’s the difference between maintained and non maintained emergency lighting? Maintained stays on permanently and non maintained can be switched on and off. Both types will switch on automatically when there is loss of power using the battery.
This installation was supplied by a 230V with overload protection in the form of a 6A Type B MCB wired using 1.5mm twin and earth which was already installed.
