Best to use mfr nameplate ratings where possible, allow for motor
startup current where appropriate, and bear in mind the National
Electrical Code assumes certain load values per 'utility' outlet and
mandates dedicated circuits for some types of equipment so you might
want to research the assumptions in whatever code applies to you before
doing too much calculation.
