and higher breaker rating may be used. There may be variances on specific systems supplied to OEM

Circuit Breakers
The breaker should be of the manual reset type that is typical of the RV/Marine industries usage.
This should be of the "slow blow or trip type" to avoid nuisance tripping due to current surges common
to the hydraulic pump motor start up. These surges may be many times the normal pump amperage
generally lasting only milliseconds.
Note: if a fuse is used in lieu of a breaker, a "slow blow" type of higher amperage rating is
recommended to prevent nuisance "blowing" of the fuse.
The purpose of the breaker is to provide protection against shorting to ground of the positive feed to
the pump assembly. It is not needed for system overload protection which is provided by the hydraulic
systems relief circuit.
Battery Type and Size
A minimum group 24 RV/marine type battery is recommended. Battery rating should be a minimum
100 RC (Reserve capacity) with a 500 CCA (Cold Cranking Amperage). The higher these numbers
the better. Common types are flooded lead acid, Gel and AGM (Absorbed Glass Mat).
Note: Some lithium batteries are not suited for this application. As they cannot provide the high
running amperage and surges. Check with the battery supplier/manufacture for info on this.
There may be additional wiring at the pump or near the control panel for specific OEM requirements.

Battery Size
Considerations
Generally, the greater the
size of the battery or bank the
better. A group 24 RV deep
cycle marine battery should
be considered the minimum.
Multiple batteries connected
in parallel is common. The
battery or bank should have
some sort of charging system
in place to keep the battery
or bank at peek charge for
proper operation.
