I have done some digging through other posts and I have a couple of queries relating to the calculation of loads on lighting circuits.
My Circuits are like this:
Circuit 1 - Futronix P800 Controller controlling Lounge, Hall, Landing
Lounge - 6 * Ceiling Lights (LV 50W Transformers)
Lounge - 4 * Wall Lights (Baynet)
Lounge - 1 * Lamp Socket (Baynet)
Hall - 2 * Picture Lights (long tubes not flourescent)
Hall - 1 * Ceiling Light (LV 50W Transformers)
Landing - 2 * Ceiling Lights (LV 50W Transformers)
16* 100W = 1600W/240 = 6.66A (not OK?)
but unless someone takes out 9 lights and changes the transformers the max would be 9*50W + 7*100W = 1150W/240 = 4.8A(OK?)
Is changing a transformer considered the sort of thign a householder would do by mistake? Just like plugging in a few brighter bulbs?
Circuit 2 - Kitchen, Shower Room, Cuboard
Kitchen - 8 * Ceiling Lights (240V GU10)
Kitchen - 2 * 50W Transformers powering 4 * 20W halogens under cupboards
Shower Room - 4 * Ceiling Lights (LV 50W Transformers)
Cuboard - 1 * pendant (Baynet)
15 * 100W = 1500W/240 = 6.25A (not OK?)
but unless someone takes out 4 lights and changes the transformers the max would be 6*50W + 9*100W = 1200W/240 = 5A(OK?)
Circuit 3 - Other Downstairs rooms
3 * Rooms with only 1*Baynet fitting in each
300W - Wow compliance
Circuit 4 - Upstairs Master Bed, EnSuite,Bed 2
Master Bed (Futronix P400) - 7 * Ceiling Lights (LV 50W Transformers)
EnSuite (Futronix P400) - 6 * Ceiling Lights (LV 50W Transformers)
EnSuite (Futroonix P400) - 1 * LED System(50W DC Transformer)
Bed 2 - 2 * Ceiling Lights (LV 50W Transformers)
Bed 2 - 1 * Lamp Socket (Baynet)
17 * 100W = 1700W/240 = 7.08A (not OK?)
but unless someone takes out 16 lights and changes the transformers the max would be 17*50W + 1*100W = 1200W/240 = 3.95A(OK?)
Circuit 5 - Master Bath, Airing Cuboard
Master Bath - 6 * Ceiling Lights (LV 50W Transformers)
Airing Cuboard - 1 * Baynet
7 * 100W = 700W/240 = 2.91A Wow Compliance again
Have I understood this correctly?
What or who is Diversity?
Does it apply and how?
Does the 100W rule apply to LV lights - even the LED one?
Thanks
Dave
