DC load calculations for marine and mobile projects
ABYC Standard E11 proposes a way to do DC load calculations for boats. The results of the basic load calculation can be used to determine the amp rating for switch panels. The data collected can then be used to calculate daily power consumption and ultimately the results can be used as a way of calculating battery size.

how to calculate max. load a nut can take?
typically when I am sizing fasteners I calculate the axial shear stress using the effective area along the pitch diameter. From there it's p/a. Once you have the load at yield apply tolerance for lubrication, surface finish and variations in material and torque application. As a rule of thumb I apply 20%, but all of your factors should be ...

Panel Loading Calculation
Another way is to install an ammeter on the feeder, and measure the load for 30 days, at 15 minute increments. Take the maximum load that you measure, add 25%, then add the proposed new load to that value. As long as you are still below 225 amps (the panel rating), you have successfully demonstrated that your new load is acceptable.
