Common Concerns Answered
What if my bilge pump draws more than 15 amps?
The 15A rating is suitable for most standard bilge pumps. For very high-draw pumps exceeding 15A, a relay should be incorporated into the wiring to manage the higher current load, protecting the switch while ensuring proper pump operation.
Is the wire length sufficient for all installations?
The included 36" wire is designed for direct connection in many common bilge configurations. For installations requiring a longer run to the power source or pump, extension wires can be utilized, ensuring a secure and appropriate connection.
How does the Attwood S3 Series compare in price to basic float switches?
While the initial purchase price may be higher than rudimentary float switches, the advanced electronic sensing technology, lack of moving parts, and superior reliability of the Attwood S3 Series offer significant long-term value by preventing premature pump wear and unnecessary service calls.
