Are you as handy with electric as you are with everything else ? For a $13 GFCI I’d rather just do it myself and know its right instead of waiting around for the guy to come back with a new GFCI from the same batch. I get wanting the work warrantied and all but a simple fix is the lesser of 2 evils IMHO.
I work with 208, 400, and 480 volt 3-phase AC at work (plus 120 and 230 V single phase, the phase-neutral voltages of 208 and 400, respectively). The biggest hazard with those voltages is not that it can kill you, after all 120 volts can do that just fine, but arc flash. Due to the voltage levels and the amount of available current at those voltage levels, if you short conductors you will get an arc flash. This is
so much fun on
so many levels. There's UV light that will damage your eyes from the arc. It's loud, which can damage your ears. And then of course the molten and vaporized copper from the wires can damage those things and everything else. It's essentially a mini explosion (there is gear that will protect you, if you wear it, at least up to certain levels). Oh yeah, and then various parts of our machines run that up to 320 kV DC. At least there's no risk of arc flash from this. So anyway, to answer your question...yes?
It's not that I can't do the work myself. It's that I specifically went with an electrician cause I had to, you know, get the pool area leveled, install the pool, install the fence, and then repair all the landscaping that got messed up. Plus while the city I live in allows homeowners to pull their own electrical permits and do their own work, you do have to take an (open book) test over the portion of the NEC that relates to the work you are doing before they will issue the permit. So I decided I'd pass on doing the electric myself to keep my plate from overflowing. My wife was getting
really antsy about getting this pool up, cause this is the
third time I've tried to set up a pool. The first two times dragged on and then we moved before the pool got up. She said that this summer the pool was getting up, and I could get it up or she'd hire someone to get it up.
So, mostly it's that because I've already paid them a significant amount of money (significant from the POV of a DIY guy), I expect the work to be done right and the devices to be functional. So on the principal of it I'm gonna call him if something he does doesn't work.
All that said, for future work where I'm not pressed for time and just need something like a circuit or two installed for X or Y, I will likely do it myself and save myself some money.
