hot tub/spa branch circuit

[bill@usps06492]

How should I calculate the proper branch circuit overcurrent protection for a hot tub. There are 4 motors drawing 1@4a,2@8.7a,1@8.3a,1@10a,and a 5.5kw heating element all at 240v.This is a residetial job and I am looking to install an 80a bkr with #2nm wire or using nm sealtight with #4thhn/thwn. I am not sure if my load and branch circuit calculations are right.

Was this home built?

There should be a nameplate with the load information, you should not have to do it yourself.
