Prior to installing the new cartridge verify that the kV rating and length matches the

cartridge being replaced. Failure to use the correct length integral cartridge will

result in poor electrical contact between the cartridge and Bay-O-Net housing

For pad-mounted transformer, the load loss and no-load loss are the same for transformers

with the same capacity, which have nothing to do with the voltage rating.
