[QUOTE="Joules, post: 536237, member: 35656"] Okay! Your inverter is acting as a household appliance. Next thing is make sure that you are safe so earthing needs to be considered. You need to get a competant person registered electrician involved to advise you about this. A difficulty you have is that when you unplug the inverter you loose the protective earth (PE) that your house is providing so your electrician may need to wire your office mains supply in a TT arrangement with a ground spike. The ground spike would connect to the earth bar in a small consumer unit and your inverter would need a permanent earth connection to it. Your office 13A sockets will be connected to the this consumer unit. 1. Is your house protected by 30mA RCD in your consumer unit? 2. Where does your mains supply to office come from, a ring main or a radial directly from your consumer unit? [/QUOTE]
