You use the correct size breaker that matches the wiring. The correct amperage will be listed in the owners manual for the tub.

What size wire is needed for 1200 amp service?

This size service can be wired in a few combinations. Two parallel runs of 1250 MCM, three parallel runs of 600 MCM, four parallel runs of 350 MCM. Of the three choices the four runs of 350 MCM wires would be the easiest to handle if there are any bends in the service entrance conduit.


What size of copper do you need for a 1250 amps rating?

There are different combination to obtain a current capacity of 1250 amps. A parallel run of #1250 MCM wires. A triple run of #600 MCM wire. The most flexible run would be with a quad run of #350 MCM wire.


What is the full load 1250 HP 4160 V motor?

129 amps


What size wire do you use when paralleled 1250amp?

When paralleling conductors for a 1250 amp load, the size of the wire depends on the application, the type of insulation, and the length of the run. Typically, for copper wire, you might use multiple runs of 2/0 AWG or larger, while aluminum wire would require larger sizes, such as 3/0 AWG or 250 kcmil, to meet the appropriate ampacity and ensure safe operation. Always refer to the National Electrical Code (NEC) and local regulations for specific sizing requirements. Additionally, consider factors like ambient temperature and installation conditions that may affect wire performance.


What gauge wire do you need for a water ground for a 600amp service?

Answer for USA, Canada and countries running a 60 Hz supply service.The answer is 3/0 copper or 250 kcmil aluminum and requires that the METAL water pipe have at least 10ft of its length in direct contact with the earth. Using a METAL water pipe as a grounding electrode also requires a supplemental electrode, which is most commonly one or more ground rods.This is NOT the way most 600A services are grounded and I recommend you consult a licensed electrician in your area to determine what is commonly done in your area.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
