Choose the number of pumps your system will utilize. For a small system below approximately 150 gpm, two pumps will suffice. Transformer Size Calculator. When sizing a transformer, you need to know the kilovolt-amps (KVA) that your machine requires. This tool will allow you calculate the KVA that you need. This tool only evaluates common voltages for North America (ie. 24v, 120v, 208v, 240v, 480v, and 600v). If you have a Eurpoean voltage or something else that is. KEB recommends using UL1283 or UL1284, high strand count cable for motor cable from the VFD to the sine filter and from the sine filter to the motor. Any cables that exit the enclosure to the motor should be shielded or in a metal conduit. The shield or conduit should be connected directly to the main ground lug of the VFD. VFD Sizing Calculator.

According to NEC (National Electric Code), IEC (International Electrotechnical Commission) and IEEE (Institute of Electrical and Electronics Engineers), a proper size of circuit breaker is must for all electrical circuits i.e. residential wiring and industrial or commercial installation to prevent. Notes to the table above. Watch out: the electric motor wire size and ampacity ratings in the table above are for lengths no greater than 25 ft. (10m) - for longer circuit runs see the next table below and also see SE CABLE & WIRE SIZES FOR LONG RUNS; Adapted from Sears, "Circuit Size for Individual Single-phases Motors", in Electrical Wiring Handbook, Sears, Roebuck & Co., April 1977. In short, the basic MOP is calculated by multiplying the rated current of the largest motor times 2.25, and adding in all other loads of 1.0 amp or more that could be in operation at the same time. MOP = [2.25 x (Rated Current of Largest Motor)] + (Other Motor Loads) + (All Heater Loads) Filter 1: If the MOP value is not an even multiple of 5. KEB recommends using UL1283 or UL1284, high strand count cable for motor cable from the VFD to the sine filter and from the sine filter to the motor. Any cables that exit the enclosure to the motor should be shielded or in a metal conduit. The shield or conduit should be connected directly to the main ground lug of the VFD.
