How do we code bidirectional RCD requirements??? Safe isolation - Skills shortage and loadsssss more

Covering the safe isolation super rod survey, EICR coding of unidirectional devices on bidirectional circuits, is there a skills shortage?
Plus we catch up with what Richard, Craig and myself have been doing.
We also discus Craigs idea to support lecturers directly around the UK (love this btw). Richard shares an exciting learning lounge and ESF link up and we answer a listeners question on the 2396 course.
