How much power (what size breaker) is required to run the grinder pump?
A grinder pump will require a 30 amp, double pole 230 volt, 4 wire service, two power, one neutral and a ground. Power and neutral should be size AWG No. 10. Ground should comply with code. M.T. I really don’t think homeowners should have the burden of added electricity bills. The operational cost for a grinder pump is approximately the equivalent to that for a 40 W light bulb. It is a very inexpensive system to operate for the service it provides. M.T. Plus in this day and age of high-energy costs and limited power on the grid, we seriously need to consider an alternative power source to run these pumps; such as a solar-powered system. You are correct. Homeowners need to be concerned with rising cost of all utilities and do anything they can to help control expenses. The cost for solar panels at this point in time would be prohibitively expensive and would have to be born by the users. The City just doesn’t have the money to provide solar panels to run property owners’ grinder pumps.
