Abstract:
This study reports test results from RFI testing of electrical junction boxes with bolt-on covers. A number of cover-gasket configurations were tested. Tests indicate that a large improvement in the shielding effectiveness of junction boxes can be obtained by increasing the number of cover bolts or using a Metex combo strip gasket. A simple field fix that provides a large increase in shielding effectiveness can be made by doubling the number of cover bolts used on the junction boxes.
