4.) CALCULATIONS AND DATA SHEETS
4.1) HEATER POWER & VOLTAGE RATINGS
LB 40-60 Model units use 2 Heaters to meet the required (KW) POWER from the
customer's specified INPUT VOLTAGE. Each heater comes in 3 different (KW) POWER
RATINGS and 4 different VOLTAGE RATINGS.
NOTE: SINGLE PHASE is NOT usually OFFERED for 40KW+ generators, because of
the extra cost to run and build with the higher amp draw requirements. Although not offered, in
some special cases single phase 40KW+ generators can be made.

NOTE: 380-425V heaters are not usually rated for 380-425V. They are usually 208-240V heaters
that have been re-stamped 380-425V and jumpered in series.

4.2) TOTAL POWER RATING CALCULATIONS

The HEATER POWER RATING and NUMBER OF HEATERS are used to calculate the
TOTAL POWER RATING. Since the HEATER POWER RATINGS are in Kilowatts, they
must be multiplied by 1000 to convert them to Watts.
