I plan to replace the central spots in a bathroom with low voltage down-lighters. Most transformers seem to have loop-in, loop-out primary inputs whereas my ceiling rose is a simple spur from the switch. Do I need a special transformer or can single L and N terminals on a loop-in, loop-out transformer be used. I plan to install 6x35VA MR16 lights via 2 105VA transformers.
the switch will act as normal and switch the transformer on and of as it should do. As it is in a bathroom i'd suggest you take a look at projects pages concerning Part P of building regs.
And it's not low voltage! Low Voltage is between 50v-1000v
Your talking about Extra low voltage which is under 50volts
