(4)gang meter banks

[Nees]

I'm working on a old trailerpark and when i do the service calculation it seems to low.I went to 550.31 which tells me to give each unit 16,000va,times 4 is 64,000 .The demand factor is 39%=24960/by 240=104amps,it seems to low to feed 4 100 breakers.Can someone let me know if it sounds right to them.Thanks

If 16,000 is larger than the actual trailer load, then your calculation is correct. That doesn't mean that you shouldn't use your own judgement when sizing the service, and provide more than 104 amps of service load.

Even though this minimum is allowed by the code, i don't think allowing 26 amps per trailer is nearly enough.
