RULE A-ﾏﾁｯｸｵｰﾄｽｲｯﾁ 40A

Q: Where is the built in test feature?

Hello Michael, The test lever is on the rear, left side near the wires. Regards, Xylem.

Q: How long are the lead wires

Hello, The wires on all of our Rule float switches are 28" long. Regards, Rule.

Q: I have an older version of this that has a turn able knob on the side. Any idea what this is used for?

Hello, The older float switch has a knob on the side so you can rotate and lift up the float inside to test the system. Regards, Xylem.

Q: Is the hole spacing (and/or general dimensions) the same as on the older mercury switch rule-a-matic plus model?

Hello Matthew, The new float switch is slightly different from the old mercury float switch. The mercury switch has a different hole pattern so you will only be able to use one of the holes from the old switch. Regards, Xylem.
