maximum demand and diversity

[scotsparky]

Am I being silly here? Where does the 16A socket rating come from?

The 16a socket rating is the assumed maximum demand for each leg of a ring circuit. 16x2+32A
This is why you can wire in 2.5mm as its classed as a duel feed of 16A per leg.

Now i'm confused! Is it the 1st socket rating(13a) on a ring and then 40% of all the other sockets on that ring(13- 60% = 5.2?) or 32A fuse minus a rule of thumb 40% diversity per ring?

hi looking for help, not best at working out answer would be much appreciated. Applying diversity to this circuit one 5.5kw 3 phase induction motor for gas hot air ducting system having power factor 0.75. efficiency 90 %

That is what i understand it to be.

me too. use the circuit breaker rating, irrespective of how many outlets, ring or radial.
