Bushing Adapter Caps
The Bushing Adaptors are shipped with a plastic-threaded cap as shown in Figure 5-7.

When removing the original test tap caps from the bushings, first check that they fit the
plastic-threaded cap from the new bushing adapter. If it is a good fit, continue with the
Bushing Adaptor installation. If the original test tap cap does not fit the plastic-threaded
cap, halt the installation and contact GE Technical Support.
Install a Bushing Adaptor
To install a Bushing Adaptor:
See Appendix D for the test procedure on how to verify the circuit integrity of the
Bushing Adaptor.
Check Bushing ID reference against Bushing Adaptor ID reference.
WARNING: After connecting the Bushing Adaptor, it is crucial that the
Bushing Adaptor circuit integrity tests in Appendix D are performed.
Remove the bushing test tap covers. Retain the tap covers in a safe place because they
will be required in the future when decommissioning the product.
With clean hands, put the smaller O-ring in its seat as shown in Figure 5-6.
Note: There are two spare O-rings supplied in the shipping package of each Bushing
Adaptor. Store these safely for future use should the Bushing Adaptor need to
be re-installed.
Apply the conductive grease to the bushing adaptor threads. The high temperature anti-
seize carbon conductive grease (supplied with the installation kit) must reach all
threads. To start, apply an even amount of grease to the first few threads as shown in
Figure 5-8.
