Power supply cable size for elite 24

[RobTi]

Hi I wired this up with 2.5 t&e but have since then fitted a new socket below the panel that I want to connect into, but wondered because of the load dropping down to 1.5 t&e or should I stay with the 2.5 t&e ?
Thanks

could mods delete please I reposted in the electric forum as more apt as it’s to do with connecting up to spur
