[QUOTE="Manator, post: 269495, member: 9561"] Richard, the design of any installation is down to cost and efficiency, with a little added what if? I never understand why some install ring circuits to bedrooms for instance, given the amount of power demanded radials are more cost effective. Just have a look now at you connected electrical devises in your own home, lets take the living room as an example. TV on? well there is no more than 5 amp, music station playing? well thats another 5 amp or maybe even 3amp. Electric fire? OK lets give that 10 amp,aquarium? another 10 amp at most for a marine setup, 5 amp for some random goldfish. Lets add all them up and we have 30 amp at most if all on at the same time. I bet the actual figure would be around 18amp, or less. Lets take a bedroom with a 3amp table lamp a 5 amp TV and you get to start to think about just how little energy all electrical items really do use. Put a clamp meter on your supply cable and turn everything on that you can, you will be amazed at the results. [/QUOTE]
