Units are 1530 Sq ft.
gas furnaces
gas ranges
elect. dryers
240v 20amp Central AC
Dish washers
Garbage Disposals
Microwave
Some (eight) w/ 120v 20amp whirlpool tubs
Some (seven) w/ 120v 5.6amp trash compactors
1 House panel for outside lighting and outlet power for maintenance
Load is approximately 30-50 amps not continuous.
There are two seperate 22 unit buildings. The meters are currently located outside and they will remain outside. One buildings meters will be relocated to a new location on the other end of the building. The other buildings meter location will not change unless new service equipment cannot meet clearances. The space is 47 inches deep with a window above at approximately 8 feet.
1) Just checking my math.
What is the demand for each unit?
What is the service size?
2) From the service equipment there are long runs to each panel location.
Can I put multiple feeders in one pipe. Do I have to derate or does
the standard wire size for services allow me to maintain that size wire
not needing to account for derating.
Am I correct in thinking that emt will surfice for a ground eliminating
the need for this wire.
3) The owners would like to keep their existing panels as most of them
are rated 125amps. Those that are not will be changed (apprx.6).
They are existing equipment so would this pass code requirements
despite the neutrals and grounds being mixed together and the age
of the equipment (20-30yrs).
4) Where would you price out the meter bank (national/local supply
house)
My two local supply houses don't have a lot of experience with this
size project. Should I ask for "In House Sales", "Outside"?
Any recommendations for best service equipment to use.
Thanks in advance.
