Radial Circuit in Attic

[Rickking4252]

I am considering installing a radial circuit from the CU on a 20a MCB to the attic to provide plug sockets in that area for TV boosters. What is the process please?

What is the anticipated load of the boosters ?
Why have you chosen a 20A MCB ?
What is the length of circuit ?
What type of earthing system do you have ?
Will the cable be buried anywhere ?
Is there existing RCD protection at the CU ?
Is your earthing and main protective bonding up to current requirements ?
Are you aware of the notification requirements ?

Can you not feed the boosters from the lighting circuit ?

Can I cut into the lighting circuit, add a junc box and run a cable to a plug socket to power the TV signal booster?

it would be much more sensible to break into the lighting circuit and add a 3amp FCU, to stop someone later on coming along and plugging a 2kw convection heater into your 6amp lighting circuit.

I would also try to avoid breaking into an existing cable and find a JB / rose you can take a twin and earth from
