Wiring this device is the responsibility of the installer.
This device is not included in any Single Point
Power options. Fig. 2-62 represents a typical electric
humidifier panel layout. The supply power knockout
is located in the bottom of the electrical panel as seen
in Fig. 2-63. All conduit beginning or ending inside
pressurized or conditioned areas (i.e. air handler) must
have all openings of conduit sealed to prevent air from
passing through. All air handling unit penetrations
must be sealed to prevent air and water leakage
(see
IOM Section 5 “Penetrations and Grommet Details”) .
Field provided disconnects must provide circuit
protection according to the humidifier nameplate. All
field wiring to the humidifier must be in accordance
with NEC and local codes and by laws.
