Power Connection Kits For Premium Series (5500)

265 or 277 Volt Installations

National Electrical Code (Article 440 section G) requires permanent connection for installation on circuit in excess of 250 volts.

Permanent Connection Kits are available for 265 volt installations. The regular kit consists of a self-aligning 9-pin connector that plugs into a mating connector on the chassis, a length of power cord with the plug cap molded to the end. There are four 265 volt cord sets so that the desired heater KW will be achieved when the correct RAK5*** kit is selected. See chart below for guide. These cord sets will match the receptacle in the RAK204E Series sub-base. It is important that care be used in this selection process. This cord set, when used with the appropriate sub-base with provided chase way from the junction box to the sub-base, is considered to be permanently connected.

For those installations that require a method of direct connection using flexible or rigid conduit, the RAK4002B junction box (provided with chassis) can be used and the field supplied conduit attached to it. The universal cord set will be cut off and connections made inside the junction box.

See page 44 for total connected load for 5500 series units.

Electrical Wiring Information - 2500/3500/5500 Series

All Zoneline units are single phase 60 hertz units.

For all installations feeder, sub-feeder, branch circuit and electrical protective devices and selection must conform to the National Electrical Code and to local codes.

Maximum connected load in amperes, including demands for the electric heater and the fan motor, are shown on page 44. Branch circuit ampacity and electrical protective device sizing are shown on page 42 for 230/208 volt units and on this page for 265 volt units. (Although presented with Premium 5500 Series this information also is valid for Deluxe Series 2500 and 3500 Series units.)

More than one unit per branch circuit is not recommended; however, when in doubt, consult the National Electrical Code. All wiring, including installation of receptacle, must conform to local electrical regulations and codes.

Replacement of Existing Chassis

230/208 Volt and 265 Volt Units

There have been changes to NEC and improvements and modifications to the Zoneline chassis and sub-bases since the unit was first introduced. Some of these changes require alterations to be made when replacing an older unit with a new chassis.

Line Cord Connected Units

The plug configuration of new line cord connected units complies with the current NEC standards. Older installations may have wall receptacles that conformed to NEC standards at the time the building was constructed and may not match the configuration of the plug on the new line cord. Recommended solution is to change the wall receptacle to conform to current standard plug configuration. See chart on page 42 for current receptacle configuration.

Permanent Connected Units With Sub-base

If the existing unit is connected to a sub-base the installation of the new unit may involve modifying the existing installation slightly. It is recommended these modifications be made by a qualified electrician.

If the existing sub-base is the full width of the wall case, RAK201 sub-base access plate may be ordered and used to replace the cover on the old sub-base. Field supplied wiring, conduit and conduit connectors should be used to make connection between new chassis and the center knockout of the RAK201. The wiring connections should be made inside the sub-base and the RAK201 attached to the sub-base with the 2 screws provided.

If the existing sub-base is not the full width of the wall case the electrician will have to modify the existing cover plate to allow field supplied wiring, conduit, and conduit connectors to be run from the permanent connection kit to the sub-base.
