To Choose the Proper Transfer Switch:
- Total Watts of light and appliances to be used.
- To that amount add the start-up watts of the largest motor.
- Add 25% to total
The Maximum Total Connected Load from the Utility
is as follows:
MTS 3024 on 120V is 2880W
MTS 4048 on 120V is 3840W
MTS 3024 on 120/240V is 5760W
MTS 4048 on 120/240V is 7680W
MTS 6048 on 120/240V is 11,500W
MTS 1001220 on 120/240V is 20,200W
MTS 1251220 on 120/240V is 24,000W
A smaller generator than the total connected load can be
used by turning off some of the breakers when the appliance or lights are not needed.
Always use a generator that is at least 25% larger than most necessary loads.
This will allow for some of the non-essential loads to be used at convenience.
