How We Calculate MCA & MOP
Use carefully. This program will calculate combinations which are not available from Titus. Titus guarantees this calculator to be accurate for all motor & heater products in our most recent catalog. The MOPulator should be accurate for any other single-motor blower/heater products up to 110 Amps MOP. Titus will not be responsible for any misuse of the calculator or use in calculating non-Titus products.
