[QUOTE="SPECIAL LOCATION, post: 501481, member: 250"] You are thinking on the right lines that diversity will actually result in a far lower load than just adding up all of the connected appliances.. Even if appliances are on simultaneously, not all appliances pull their full load all of the time.. e.g. a washing machine just rotating the drum takes far less than when it is heating water for a 60degeree wash! And kettles & toasters will only be on for a short time.... Have you got a basic clamp meter you could put around one of your meter tails.. e.g. [URL="https://www.amazon.co.uk/Proster-Digital-Clamp-Meter-Capacitance/dp/B0821GZK9H/ref=sr_1_8?dchild=1&hvadid=80607978339994&hvbmt=be&hvdev=c&hvqmt=e&keywords=clamp+meter&qid=1598517706&sr=8-8&tag=mh0a9-21"]https://www.amazon.co.uk/Proster-Digital-Clamp-Meter-Capacitance/dp/B0821GZK9H/ref=sr_1_8?[/URL] to see how much current is actually flowing? The bottom line is providing the cable and protective device are correct for the circuit then worst case the MCB trips.. but reality is it will takes a fair bit more than 32A to trip the MCB.. If a short period of higher current did occur it would not be a problem... [/QUOTE]
