16 years as a Mechanical Hydraulic Engineering Tech from aviation background. Now working 8+ years on ROV's with 3000Vac /3 phase - input of 440Vac at 250A from rig or ship, down to single phase 12Vdc. Did some basic courses in electrics during training for ROV's, but have learnt a lot more in 8+ years on the job.
Haven't a clue about domestic electrics compared to professional electricians on here, but would rather be honest and get a qualified sparky in to resolve any domestic electric issues I have.
I can wire a plug, and trace faults, so not completely clueless, but still - if I'm not sure - I play it safe and call a qualified sparky.
So I'd put myself as a mech/hyd tech first, but with working knowledge of some industrial surface and subsea electrics.
