Back floodlight - 1.5 to 2.5 cable

[ssl0kxp]

HI,

Can anybody tell me what the implications (if any) of extended a lighting circuit (1.5 cable) to feed an outside light (150 Watts max), using a 2.5 arctic cable for the 'through the wall' outside connection? All other cable to and from the (new) switch will be 1.5.

why do you want to? i mean, why use bigger cable than you have to?

Only because I have a couple of meters of 2.5arctic and do not want to use T&E on the outside of the house which, will not form the best watertight seal on the light fitting...

No problem as long as there is enough room to terminate it

fair enough
