Does a 70W 6ft fluorescent batten fitting actually 'consume' 70W, or is it just the lamp which 'consumes' 70W with extra losses to be accounted for in the control gear (ie additional losses in the choke etc)? Initial stages of looking at reducing energy bills for a warehouse. Old fluo battens...

Replaced an old Wylex fuseboard (BS3036 fuses) the other day. TNCS supply with Ze 0.14ohm. I was expecting fast rcd trip times on x1 and x5, but x1 are surprisingly high. Tried 0 and 180. Examples of some of the readings: Sockets (ring) Zs 0.28ohm, RCD 43ms@x1 and 22ms@x5. Sockets (radial)...
