    Spurring off FCU supply side

    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
