BONDING METHODS SHALL BE CLASSED AS FOLLOWS:

CLASS A - A BOND THAT IS ESTABLISHED BY JOINING TWO

METALLIC SURFACES THROUGH THE PROCESS OF

WELDING OR BRAZING.

CLASS B - A BOND OF 0.1 OHM (DIRECT CURRENT (DC)

RESISTANCE) OR LESS THAT IS ESTABLISHED

BETWEEN AN EQUIPMENT HOUSING, CASE OR CABINET

AND GROUND POTENTIAL, AS A RESULT OF THE

INSTALLATION OF THAT EQUIPMENT OR AS A RESULT

OF THE PREPARATION OF THE MOUNTING SURFACE.

CLASS C - A BOND THAT IS ESTABLISHED BY BRIDGING TWO

METALLIC SURFACES WITH A METALLIC BOND STRAP.

THIS DRAWING ADDRESSES CLASS B AND C BONDING ONLY.

ON BELOW DECKS (WEATHER PROTECTED) INSTALLED EQUIPMENT,

A BRIGHT METAL CONTACT AREA SHALL BE PROVIDED BOTH ON

THE EQUIPMENT MOUNTING SURFACE AND ON THE MOUNTING

FOUNDATION. THIS BRIGHT METAL CONTACT AREA SHALL BE

PROVIDED AROUND AT LEAST ONE MOUNTING BOLT AND SHALL BE

AT LEAST EQUAL IN SIZE TO TWO MOUNTING BOLT DIAMETERS.

A METALIZED CONDUCTIVE GASKET SHALL BE CUT AND FITIED

TO THE BRIGHT METAL AREA. THE EQUIPMENT SHALL BE ~

INSTALLED AND TESTED FOR A 0.1 OHM OR LESS DC ~

RESISTANCE. ON ABOVE DECK (WEATHER EXPOSED) EQUIPMENT

WHERE A 0.1 OHM DC RESISTANCE IS NOT INHERENT IN THE

EQUIPMENT INSTALLATION, THEN A CLASS C BOND SHALL BE

INSTALLED BETWEEN THE EQUIPMENT AND GROUND POTENTIAL.

6. CLASS C BONDING (VIA STRAPS) SHALL USE ONE OF THE

FOLLOWING TYPES OF STRAPS:

TYPE I - TYPE I BOND STRAPS ARE FOR USE IN SHIPBOARD

TOPSIDE AREAS FOR BONDING EQUIPMENT WHERE

CLASS A BONDING CANNOT BE ACCOMPLISHED. SEE

FIGURE 1 AND NOTE F1 FOR FABRICATION DETAILS.

TYPE II - TYPE II BOND STRAPS ARE FOR USE IN SHIPBOARD
