Spurring off FCU supply side

[wassupjg]

Hi, apologies for the basic question

In a radial circuit, is it permissable to spur off the supply side of an existing fused connection unit?

As above, 3A FCU is feeding a floodlight, is it okay to spur off the supply side of the 3A FCU to feed a 13A FCU, isolating an outdoor socket?

Cheers

Yes… as long as the initial radial circuit is designed properly regarding OCPD, cable size and rcd protection.
