cord entry plate with molded pins to conduct electricity eliminating the ability of water to enter internally through the cord. The motor shall
be protected on the lower side with a unitized ceramic/carbon seal with stainless steel housings and spring. The upper and lower bearing

accordance with the National Electric Code. The power cable shall not enter the motor housing directly but will conduct electricity to the
motor by means of a water tight compression fitting cord plate assembly, with molded pins to conduct electricity. This will eliminate the
ability of water to enter internally through the cord, by means of a damaged or wicking cord.
