Hi to everyone on the forum.
I am new to this forum and I am currently a trainee electrician. I love everything about the electrical industry and would like to start building knowledge with work colleague and forums when need to ask certain questions about jobs.Â
Â
So the 1st question I have is how much load can be on a ring main. Doing a simple calculation V*I I get 7680watts. But how does this work with diversity and in a kitchen ring main. My parents have had there kitchen renovated with painted doors and new work tops but have added in a larder unit which will house a combi microwave/grill. Now I am looking to plug this into the existing Kitchen ring main. The current house set up isÂ
Oven/cooker - 32amp MCB
1st floor sockets - 32amp MCB
2nd floor sockets - 32amp MCB
kitchen/utility sockets - 32amp MCB
1st floor lights - 6ampÂ
2nd floor lights - 6amp
heating - 6ampÂ
currently on the kitchen/utility ring isÂ
washing machine - 2.2kwÂ
dishwasher - 2.1kwÂ
drier - 2.2kwÂ
cooker hood - 80watts
utilty fan- 30wattÂ
kettle - 3kwÂ
toaster 1.5kwÂ
1xdouble socketÂ
now directly behind the larder unit is the double socket which I am looking to use for plugging in Mico/grill combi which is rated at 2.1kw. Will this be ok to do with all other appliances plugged into the same ring main. As I have added up roughly 12 kw with adding appliances above together plus the new mico/grill on this ring main but I know I was told about something that they will not be pulling full load all the time so that is why diversity comes in, so a ring main could supply a lot of appliances as they will not be pulling full load at same intervals. Reason trying to avoid pulling new cable in consumer unit is about 20metres away with concrete ceiling and new hard wood flooring. Just hoping this will be suitable and not cause issues. Hope that makes sense. Responses will be very grateful
