[QUOTE="kme, post: 15308, member: 113"] Okay `tash. Sorry for any mistakes - it`s late & i`ve been at the wine bottle. 8 60w blubs=480w 12 lv? what lv are they? led? lv halogen? The voltage doesn`t matter AT ALL! the total wattage is the figure you need. The LED`s would probably be max 3W LV halogen dichroic 20 or 35 lets say 35W halogen. 35 X 12 =420W + 480 from earlier =900W @230v =3.9A Even if you could draw 32A from you "garage ring" (WHY!!!) that`s still 36A make the garage a 20A radial. external lighting (and internal, for that matter) can go on 6A generally (unless specifics dictate otherwise) Don`t forget, that outside lighting figure doesn`t include diveristy, at 2/3 (66%) your house "rings"- again WHY? Other than kitchen/util, you could put the whole of the house on a 16A radial (normal sized house; not 50 bed mansion), and you won`t EVER trip it!!! HTH KME [/QUOTE]
