Where do this thoughts come from, Winston? Is it drugs with you or just guesswork?A radial generally has more than one outlet.
A simple examples of Radial circuits.
Immersion heater = one outlet
Cooker circuit = one outlet
Shower circuit - one outlet
By your definition none of these circuits are radials. They certainly are not ring final circuits. What would you call a circuit that has one cable leaving the the consumer unit and only goes to one place then? A rad, an ial??
