Power Connection For Deluxe
Series (2500 & 3500)
The Zoneline 2500 and 3500 Series units have discrete heater
wattages. Each unit has a factory installed heater and must be
installed on an electrical circuit with sufficient over-current
protection to carry the amperage load of the unit. See
specifications on page 54 for model number nomenclature,
heater amperage, and minimum circuit ampacity for the
particular Zoneline model. To determine maximum
connected load for individual model see page 44.
230/208 Volt Unit Installation - Line Cord Connected Units
Zoneline 2500 and 3500 series units for installation on 230 or
208 volt circuits have a factory installed line cord with a plug
conforming to NEC standards for the circuit amperage.
Graphic representation of the wall receptacles are shown on
page 42. The line cord length is also shown on page 42.
230/208 Volt Unit Installation - Permanent Connected Units
If a permanent, or direct wired, installation of a 230 or 208
volt units is desired, a junction box kit, RAK4002A, is
available to allow direct connection when the 208/230 volt
chassis is installed with the appropriate electrical sub-base.
When the cord set is enclosed by the RAK4002A and the
sub-base chase way RAK205CW, the wiring is totally enclosed
and the unit is considered to be permanently connected
(correct ampacity RAK204 series sub-base required).
If an installation using flexible conduit is desired, the
RAK4002A kit mounts to the chassis to form an enclosed
junction box with a removable front panel for access to the
unit wiring. A 7/8" diameter hole in the bottom of the
enclosure enables field supplied rigid or flexible conduit to
be connected to the kit. A wiring harness of three conductors
and an in-line connector is included with the RAK4002A.
The factory installed line cord must be cut off approximately
8" from where it comes through the barrier, or bulkhead, of
the unit. Strip insulation off 3/4" of each conductor to expose
wire for field connection. These wires are then connected to
the building wiring by field supplied connectors.
265 or 277 Volt Unit Installation - Permanent Connected
Units
National Electric Code (Article 440 Section G) requires
permanent connection for units connected to power sources
over 250 volts, therefore these units must be permanently
connected (direct wired).
Zoneline 2500 or 3500 Series units rated for installation on
265 volt circuits have discrete heater wattages and the
appropriate cord set to match the 265 volt sub-base
receptacle installed in this sub-base. When installed with the
correct sub-base and chaseway the wiring is totally enclosed
and the installation is considered to be permanently
connected. If there are any questions regarding electrical
connection at the unit GE recommends consulting with your
local electrical inspector.
A junction box is included with every 265/277 volt chassis to
facilitate the installation of conduit if desired. A 7/8"
diameter hole in the bottom of the RAK4002A junction box
enables field supplied rigid or flexible conduit to be
connected to the unit. A knockout is provided in the junction
box for the installation of a field supplied cartridge type fuse,
if required. A wiring harness of three conductors and an in-
line connector is included with the RAK4002A. This wiring
harness can be ordered separately as RAK4002CW to facilitate
chassis removal.
When direct connecting the unit, connections to the
building wiring should be made in the junction box with
field supplied connectors.
All wiring must conform to local electrical regulations and
codes.
