Questions about this item
What does the 8.300 rating mean when the float switch is installed in a bilge system?
The 8.300 designation identifies the Rule 40A-GRA as an automatic marine float switch designed to activate a pump when water reaches a set level and shut it off when the level drops.
How do the 12VAC, 24VAC and 32VAC ratings limit the control voltage I can use with this switch?
The switch is rated for control circuits up to 32 volts AC; applying a higher voltage would exceed its rating and could damage the contacts.
