OSG Standard Circuits - 3A lighting

Current Bun:

As we are all using led lamps / fittings now it seems this should be a standard circuit.

3A MCB with 1.0/1.0 cable


Lighting circuits used to be based on 100w incandescent lamp / room at 1800 lumens which is equiv to 20w led.

What are the figures for max distance for a 3A type B using 1.0/1.0 as an addition in table 7.1 page 66 in OSG?

I wonder if many new L.E.D. lamps on one circuit may create a high initial inrush current when first turned on, that may trip a B3 breaker.
