 Technical Data

Submersible Motor Data

Single Phase Motor Fuse Sizing: 20amp Breaker, Standard Fuse: 25amp or dual Element Time Delay Fuse: 15amp.

Submersible motors should not be cycled on and off in excess of 1 time in 5 minutes and be limited to 25-50 starts in 24 hours.

A (3) wire submersible motor requires a minimum of 10 seconds between starts for the internal start/run switch to reset.

Engine driven generator requirements - External Regulated: KW: 3.0, KVA: 3.8 - Internally Regulated: KW: 2.0, KVA: 2.5

Note: Generator should always be running before motor connected. Before stopping a pump, shut off pump before turning off generator. Most generators today are of the external regulated type. Internal regulated generators have an internal winding and it controls the output current.
