[QUOTE="brummydave, post: 545945, member: 18490"] Some manufacturers say you can take the live from any circuit, it doesn't have to be a dedicated MCB. Others say no MCB required, amazingly, but pretty much all would agree that having some sort of isolation - in this case Main Switch - is a necessity. Have a look at surge devices website for more info on different connection option. [/QUOTE]
