Before you order
Work from the prime rating, not the standby rating, when sizing for daily use. Larger engines are supplied to order, so send us your requirements and we will quote with lead time.
Not sure it is the right one? A photo of the old part and the nameplate of the machine it came off is usually all the counter needs to confirm a match.
Questions
What is the difference between prime and standby power?
Prime power is the rating for running with a varying load for unlimited hours. Standby power is a higher rating for emergency use when the mains fails, with limited hours per year.
