## Diversity Calculator Description
Calculate the maximum demand, total full load and apply diversity. 

Enter your load values in Amps, Watts or kW, for three phase also select the phase for which the load applies to: L1, L2, L3 or L123.

Calculation Reults:
- Total Full Load
- DL 1 (osg)= Calculates diversity based on the OSG.
- DL 1 (custom) = Set your own diversity factor.
- DL 2 = Applies the rule of thumb method.
- DL 3 = Apply a usage factor to DL 1 (OSG).

Other Features:
- Custom Circuit: You can enter your own diversity factor and circuit description for "custom circuits".
- Edit the default PF (power factor) value for applicable three phase circuits.
- Print all results.

How to calculate single phase diversity:
1) Select the distribution board type  (Single Phase, Three Phase).
2) Select the type of premises.
3) Select the description of circuit / load.
4) Enter the load value (kW, Watts, Amps).
5) Add Load
 
How to calculate three phase diversity:
1) As above but with the additional options to select phase, L1, L2 L3 or L123.

A single phase (230v) and three phase (400v) diversity calculator.

When adding multiple loads of the same type i.e. Cookers, socket-outlets etc. always enter the biggest load first, then the second largest load and then finally the remainder of the loads.

This diversity calculator ( = DL 1 (osg) ) is based on the 18th edition On-Site Guide. The diversity calculations results with 3 results based on 3 different methods on applying and calculating diversity.
