Utility service size or sub-panel rating If the generator will only be backing up a sub-panel, then select the sub-panel rating. The Power Company Meter in the diagram above should then be considered the upstream panel.

from new ATS to new generator

Generator model numbers are Cummins QuietConnect and PowerConnect series.
Generally, for single phase generators kVA=kW.  For 3 phase kVA=kW÷0.8 if rated at 0.8 pf.

    
This should be the line-to-line voltage for split-phase and 3 phase systems.

  labor billing rate This is the rate billed by the contracting company which includes overhead and expenses. It is more than just the electrician's net hourly wage. For the detailed article Pricing Service Work for Profit click the question mark.
 material markup

 % sales tax on labor  Enter as a percentage. Many states do NOT charge sales tax on material. Enter 0 if no tax is to be charged.
 material purchase trips
 prep site for generator
 move & mount generator
 drill & mount enclosure Automatic transfer switch must be mounted along with 1 or 2 load management contactor enclosures. This is the average time it takes to mount 1 enclosure. Do not include wiring time.

trencher rental cost If you own a trencher then this can be set to $0 or set to the time-value of the machine.
 pickup and return trencher
 electrical permit cost Set to $0 if no permit is required, or if others will be taking care of this.
 prepare and submit permit
 disconnect & remove serv cable
dig around buried lines If there are other buried utilities where you cannot use a trenching machine select the time it will take to hand dig those areas. Also include any time necessary to hand dig end of trenches.
final test and startup Include final system checks, testing and startup time.

conduit length Buried conduit length is the horizontal distance plus 5' to come up out of ground and reach termination point on each end. However, if horizontal distance is less than 5' it is assumed that the conduit is NOT buried and this adder is not applied to each end.
wire length Wire length is assumed to extend 2.5' beyond the ends of conduit.

  1. Printing Help: You may need to decrease the displayed font size in your browser to improve print readability. Press CTRL - to decrease size or CTRL + to increase. Also changing to landscape printing can improve quality.

  2. The calculation assumes uncoated all copper stranded conductors in PVC schedule 40 conduit.  The Ampacity is based on NEC 2011 Table 310.15(B)(16) for 75C insulated conductors rated 0 through 2000 volts with not more than three current carrying conductors in raceway, cable or earth with an ambient of 30C (86F). Conduit sizes selected based on NEC Table C.10 for THWN conductors.

UPDATES:
06/07/2017 Improved unit labels and two time assumptions, changed kVA menu to kW and updated FLA formulas.
