8.0 INSTALLATION
The breaker must be be vertical, level and securely fastened. Follow your company guidelines
and codes for setting the height of the breaker, securing the frame to the pole or foundation, and
making connections.
8.1 Mounting
The breaker is normally shipped suitable for substation mounting. The following is the recom-
mended installation procedure:
Substation Mounting:
1. With the lifting brackets mounted to the breaker roof, lift the breaker off the pallet and move
into position.
2. Bolt the legs to the pad and raise the upper portion to the desired height.
3. Bolt the legs to the sides of the breaker.
4. Make sure all hardware is tight.
8.2 Grounding
The breaker cabinet has two ground parts, one on each side sheet. It is important that both of
these be connected to the ground grid with #6 or larger wire. If the ground pad is provided on the
roof, it should be connected to the ground pad on the side sheet.
8.3 Arrester Protection
ABB recommends that surge arresters be properly applied in the substation.
8.4 Control Power
Supply the control power as indicated on the wiring diagram. If 240 VAC is used, verify the con-
nections for the heaters before applying power. Check all terminal block connections for proper
tightness. For details of the overall control circuit, refer to the specific wiring diagrams supplied
with the breaker.
8.5 Final Inspection
When the breaker has been installed and all mechanical and electrical connections completed,
EXCEPT ENERGIZING THE POWER LINE, the following points of inspection are recommended:
1. Ensure the breaker is properly leveled and securely anchored.
2. Make a final check of tightness of all hardware.
3. Check that the heaters work.
4. Securely tighten terminal and ground connections.
5. Check control cable entrance fittings for tightness.
6. Operate the breaker from the control box to verify normal operation.
7. Secure all doors and ensure proper gasketing for weather.
8. Ensure that all tools are removed.
