What electrical testing is required, on a newly completed domestic installation according to your NEC code requirements??

Get the journeyman to switch it on, with you a safe distance away .........

it depends on the inspector, most common is a ground rod test with a 3 pin tester, and test with a "megger" [mega-ohm meter] phase to phase,
phase to neutral, and phase to ground and neutral to ground for feeders only, not for the branch circuits. and voltage test everything. none of this is required by NEC. here our work is inspected by 3 different agencies who apply rules which are sometimes above and beyond the NEC, which is their right
as the AJD [authority having jurisdiction].

That's exactly as i know it, not much in the way of testing at all!!!
To say minimal i guess would be a bit of an understatement when compared with the requirements to your European counterparts accross the pond...

Watched a program called Holme on Homes based in Canada and the electrician fitted a GFI(RCD) and said it should be tested every month not 3 as in this country.

As far as i can remember... in households, they are only required for outdoor receptacles and bathroom receptacles, i could be wrong there, but not too far out!!! They certainly don't make use of RCD devices as we do in Europe. Tripping value is 6mA, and mainly incorporated in the receptacle outlets, although some circuits will be supplied by RCBO type breakers in the enormous DB panels....

the trip setting on our gfci outlets is 5mA designed to be below the lethal shock level. Us Yanks dont see the advantage of a trip level of 30 or 300mA which would allow a lethal shock without tripping.
The new thing here is AFCI [arc fault circuit interrupters] designed to prevent fires due to sparking.
BTW, im from California, but have been working in the Mid East for 3 years where im learning 17th ed. The difficultest part is the terminology is different for every little thing.
