At what point do you call an electrician?
Here's my situation: I need to run a new power cable to a ceiling-mounted projector. The guys who installed it did the whole "let's run some two-core flex from socket to projector, meaning any new projectors requiring three-core are out of luck" routine.
I'm going to get some flex, wire a plug on one end and a single or double socket onto the other. Now, it's easy as pie, being a single step above wiring a plug. I've got no worries about my abilities in the matter, but the head of ICT has expressed concerns over responsibility and accountability, and other 'ility's.
On the sliding scale between wiring a plug, and installing a new ring circuit, where do you draw the line and call in a sparky?
