In this video we go through step by step the calculation for working out maximum demand and diversity for a single phase installation. For this version of the calculation we take 100% of the largest circuit fuse rating and 40% of the sun of all the other fuse ratings and add these numbers together to find the maximum demand for the installation. == 🕐 Time Stamps - Cut to the action 🕕 == 00:00 - Maximum demand and diversity 00:18 - Easy calculation on-site 00:38 - Old circuits 00:47 - New heaters 01:10 - Don't want to blow the 100 amps fuse 01:33 - 100% of the largest circuit 01:42 - 40% of the remainder 02:04 - Circuit loads without diversity 02:33 - Applying diversity to the old circuits 03:23 - Applying diversity to the new circuits 04:08 - Table in the On-Site Guide 04:21 - Comparing calculations Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.
