I assume it's OK to put an FCU (to run a light, so will be fused 3A)
on a 'radial' circuit wired with 2.5sqmm on a 20 amp breaker?

It was going to be a slightly more complicated question of a single
socket spur and an FCU on a ring circuit but then I realised it's not
a ring circuit which made me rather pleased! :-)
