Direct Power Operation

The ST3020B1/BCUL submersible pumps can be configured to operate by direct power (Figure 4) or connected to a control box (Figures 9, 10 and 11) utilizing float switches. When the pump is connected directly to a 1Ø, 230 VAC, 60 Hz power source via the L6-20P plug located at the end of the power cord, the pump will operate soon as power is applied. It is suggested that a quick disconnect switch be installed as a means of turning the power on and off.

When operating the pump using direct power (no control box) the pump must be monitored at all times. Failure to monitor the pump during operation could lead to severe pump damage should the pump encounter problems such as a stuck impeller or not fully immersed in water.
