Zeff, I can sympathise with you.I started out on an install background, but now I do maintenance.
I have found over the years that lads who come from a putting it in background morph into a maintenance post far easier than lads who trained initially in maintenance then went to install it. It's not the fault of the engineer, it is the training they received.
I applied for a teaching job with a local training centre, I had all the quals they wanted (and more) but when I saw the curriculum I questioned it. "Where's the install training" I asked. They don't need it they are maintenance, I was told.
To maintain equipment you need to know how to put it in and to me, the best way to teach a lad electrics is to teach him what he looks at every day, his own home, domestic electrics. It wasn't on the curriculum.
Domestic is the fundamental basis to all electrical work, if you aren't taught that the rest becomes detached from you.
I remember first being taught 1 way switching. That very weekend I installed some security lighting in my Grans house, which later saved her from being burgled.
