1) service supply--overhead drop or service lateral?
really up to the customer, asthetics vs. $$$$ are key
2) For an overhead, is SE cable used for the service entrance conductors (SECs)? If you have a choice of cable (SER?) or heavywall, does lower cost dictate use of cable?
#2 SEU =100A 4/0 SEU=200A, and yes it lowers costs.
3) For SECs run in pipe, is aluminum or copper used?
condutor/pipe sizing may dictate CU
5) Do you install a meter/main combo, or a meter pan and separate cutoff?
meter/main is easier, looks better too.
6) With a meter/main, do you bond the neutral and the grounding electrode conductor on the main breaker side? If so, do you run 4 conductors to the house panel (with floating neutral bar), or 3 (with neutral bar bonded to ground)?
The MBJ would be in the meter/main, a 4-conductor SER 'main feeder' would then be the norm.
7) With a meter/main, do you usually use an MLO house panel?
8) To go from meter pan to cutoff (or meter/main) to panel, do you use Sched 80 or cable (SE)?
cable is cost effective
9) Grounding electrode--for new construction, is the Ufer made of rebar, or #4 copper (or something else)?
10) GFI breakers are rarely used with all-in-ones; after all, who wants to go outside in a bathrobe to reset a tripped bathroom circuit? Is it typical to use GFI breakers with an exterior meter and interior (basement) panel?
situational, i find that external GFI's crap out fast in New England, and a breaker can do
quite a few receptacles....
11) Do you use a backer board or one-by lumber standoffs when mounting the panel on a block wall? Or is the panel fastened directly to the wall?
depends on if it's a dry or damp [dirt floor, etc] basement...
may the poll continue Cliff....
