Marking and Application Guide
3.3. PUMPS
Listing Mark. Pumps suitable for this application have a Listing Mark with the product name
―Swimming Pool Pump‖ or ―Swimming Pool Pump or Spa Pump.‖
Storable Pools Only. The type of pump suitable for use with storable pools has a 25-foot
flexible cord and attachment plug. It is marked:
―This Pump is for Use with Storable Pools Only — Do Not Use with Permanently Installed
Pools. A storable pool is constructed so that it may be readily disassembled for storage and
reassembled to its original integrity. A permanently installed pool is constructed in or on the
ground or in a building such that it cannot be readily disassembled for storage.
Field Installation:
Double Insulation. Pumps with a minimum 25-foot supply cord are double insulated and
have inaccessible metal parts grounded with the equipment-grounding conductor terminated
at the attachment plug. These pumps do not have a bonding connector. They are not
intended to be connected to an equipotential bonding grid.
Ground-Fault Protection. Pumps for storable swimming pools are provided with a factory
installed Class A ground-fault circuit-interrupter. It is an integral part of the attachment plug
or in the supply cord within 12 inches of the attachment plug.
