I am unsure about a couple things on a temp. service. The 100 amp outdoor panel is fed from 100 amp overhead meter socket with #2 Al SEU. It is only a six space panel so I do not need a disconnect or main breaker, right? I am using four spaces to feed four 20 amp gfci duplex receptacles.
Can I bug onto the utility pole ground wire? ( the service is mounted on the pole). I've seen utilities do this in the past.
 
2 awg aluminum is rated for 90 amps at 75 degrees. Whether or not you need a main in that panel is going to be dependent upon the listing of the panel. Lastly as far as the GES is concerned, unless the chosen electrode(s) qualifies per 250.52 as a recognized electrode it just isn't. (the butt-wrap on a POCO pole is not a recognized grounding electrode.)

six throws of the hand..........only using 4........OK IMHO

4 20A x .8 = 16A x 4 = 64A.......also OK IMHO

Pole is a structure.......stick 2 in the ground and go........best of all,

contact local AHJ for your area of the country.
 
The panel says it is suitable for service equipment if a main breaker is installed. Since it is a main lug only, I guess I will have to install a 2pole cb in the other slots and backfeed it. Looks like I should use an 80 amp for the main breaker; I'm used to using #2 al Seu for residential services. Thanks for your input guys.

Less than that assuming 120/240 and 2 on a and 2 on b . I would not use 80 % in this calculation as temps often are loaded to full 20
