2.4 INSTALLATION LOCATION
The wide Operating Temperature range of the RAYCHEM NGC-30 permits installation in almost
any convenient location. Considerations should include: expected atmospheric conditions
(weather), accessibility for maintenance and testing, the location of existing conduits, and
hazardous location rating. Ambient temperature conditions may affect load current ratings
.
CAUTION:
Always be sure that the intended location is classified as an area that the product is approved
for use in as defined by Article 500 of the National Electrical Code and/or Part I, Section 18 of
the Canadian Electrical Code.
2.5 MOUNTING PROCEDURES
Each RAYCHEM NGC-30 panel includes a set of “As Built” drawings that have been engineered,
designed, and drafted based upon the model number and any special requirements that
were requested when ordering. The “As Built” drawings include an elevation/layout (with
bill of materials) and schematics. If these drawings are not included, contact your nVent
Representative and request the “As Built” drawings for your panel. Upon request, an electronic
copy of these drawings can be provided.
For mounting the panel, locate the elevation and layout drawing which includes a bill of
materials. The enclosure mounting information will be provided on the “As Built” drawings.
2.6 WIRING PROCEDURES
Refer to the “As Built” drawings for wiring of incoming/outgoing power and incoming RTD
connections. The RAYCHEM NGC-30 panel can be purchased with, or without, a distribution
panel board.
2.6.1 INCOMING POWER WITH DISTRIBUTION SYSTEM
Main Circuit Breaker
Locate the main circuit breaker in the panel by using the supplied elevation/layout drawing,
and connect per the associated schematic drawings. Depending upon the size and type of
main circuit breaker and voltage loss calculations, use the appropriate size and number of
wires to connect directly to the main circuit breaker, and panel board neutral and ground bus in
thepanel.
