The manufacturer says that I should fit a double pole isolator spur before the pullcord switch/light switch. This will be very difficult because of access. Can I instead insert a three pole isolator immediately before the transformer?
Also, could I incorporate two RCD devices in the permanent live and switched live as the main supply to the house has no RCD on the consumer unit and the existing mains operated fan comes off the bedroom lighting circuit.
