Hi, this of interest to the ELECTRICIANS amongst us (Or DIYers who fit their own fusebox consumer units) here are my two XL fusebox rcd: MCB & skt wire autocalc's. ::D

Edit to suit. Both have examples. The file sizes are a bit big at 0.8mb's each, so recommend, SAVE file, then OPEN.
Simply edit fusebox mcb amps/watts (R/H of spreadsheet, columns N and O), then add in list your lighting, skts/appliances (L/H of spreadsheet, columns A to F).
I like these, give me your comments if you like these XL spreadsheets. :cool: Or post your edits!
Functional note:
If MCB max NOT exceeded, but want to start next MCB, then calculate DIFFERENCE between the MAX WATTs of that MCB, and that MCB's running total, then enter misc line for that WATTs amount.
EG: 6 "a" running total = 1300. 6 "a" Watts Max = 1440 . 1440 - 1300 = 140 Watt's difference.
HENCE: misc line, 140 Watts (See included examples, very easy to follow)
You like that? Let me know if you think that is great.
Cheers
