Appendix 1 Load Calculations
In order to calculate the kVA necessary for your application, use the following formula
from ABYC E-11:
kVA = Maximum Total Leg Amps. X System Voltage
1000
The Maximum Total Leg Amps can be calculated using the following worksheet from
ABYC E-11:
11.8.2.2.1.1
Lighting Fixtures and Receptacles - Length times width of living space
(excludes spaces exclusively for machinery and open deck areas) times 2 watts per
square foot (20 watts per square meter).
Formula:
Length (feet) x width (feet) x 2 = ________ lighting watts, or
Length (meters) x width (meters) x 20 = _________ lighting watts.
11.8.2.2.1.2
Small Appliances - Galley and Dinette Areas - Number of circuits times
1,500 watts for each 20 ampere appliance circuits.
Formula:
Number of circuits x 1,500 = _________ small appliance watts.
11.8.2.2.1.3
Total Load
Formula:
Lighting watts plus small appliance watts = _________ total watts.
11.8.2.2.1.4
Load Factor
Formula:
First 2,000 total watts at 100% = _________.
Remaining total watts x 35% = _________.
Total watts divided by system voltage = _________amperes.
11.8.2.2.2
If a shore power system is to operate on 240 volts, split and balance loads
into Leg A and Leg B. If a shore power system is to operate on 120 volts, use Leg A only.
11.8.2.2.3
Add nameplate amperes for motor and heater loads:
