Marking and Application Guide
―Hot Tub Equipment Assembly,‖ or
―Spa Equipment Assembly.‖
Field Installation:
GFCI Protection. Cord-connected equipment assemblies have GFCI protection provided.
Convertible equipment assemblies have protection provided in the 120-volt configuration.
They are protected in the 240-volt configuration, unless marked ―Connect To A Circuit
Protected By A GFCI When Connected In The 240-volt Mode‖ or the equivalent.
Permanently connected equipment assemblies may or may not have integral GFCI
protection. If not, the installation instructions indicate the unit should be connected to a
circuit protected by a GFCI. If integral GFCI protection is provided, it protects all circuits.
Disconnecting Means. A convertible or permanently connected unit may be additionally
provided with an integral disconnecting means not intended to substitute for that required by
NEC® section 680.12.
Suction Fittings. To reduce the risk of hair and body entrapment, equipment assemblies
are intended for use with a UL Listed suction fitting, the flow rate of which meets or exceeds
the flow rate marked on the equipment assembly. Each equipment assembly is marked with
―WARNING — PREVENT DROWNING‖
1. Supervise children at all times. 2. Attach spa cover after each use. Install a suction fitting
with a marked flow rate of not less than ___ gallons per minute.‖ In this case, the ___ is
filled in by the manufacturer with the gallons per minute flow rate of the assembly.
Supply Connection. These units may be designed for either permanent wiring or
connection with a flexible cord and plug. They may also be designed for field convertibility
from a 120-volt cord connected configuration to a 240-volt permanently wired configuration
only. The electrical rating includes the minimum supply conductor ampacity and the ampere
rating of the supply conductor overcurrent protective device.
Underwater Lighting Circuit. Equipment assemblies that have terminals on the load side
of a ground-fault circuit interrupter, which protects field-installed conductors of an
underwater lighting circuit, are specially marked. The markings indicate that the field-
installed conductors shall not occupy conduit, boxes or enclosures with conductors of other
circuits, unless all other conductors are also on the load side of a ground-fault circuit
interrupter. Suitable segregation or isolation of the circuits is maintained within the
equipment.
Special Markings:
Multiple Disconnects. If more than one disconnect switch is required to disconnect all
power to a unit, the unit is marked — in a place readily visible to service personnel prior to
disconnecting the main supply for the unit — with the word ―WARNING‖ and the following or
equivalent, ―PREVENT ELECTROCUTION — Disconnect all supply connections before
servicing. This appliance has _______ supply connections.‖
