See DCS for standoff bracket placement and grounding requirements. 5. Some standoff brackets require that one of the nuts on the double arming bolt be replaced with a jam nut. The jam nut should then be inserted into the 5/8 slot on the standoff bracket. If the nut on the double arming bolt will fit into the 5/8 slot on the bracket Do Not Use the jam nut. 6. On the front of the 20 standoff bracket, the following conduits may be mounted: 4 2 conduits, 3 2 1/2 conduits, 3 3 conduits, 3 conduits, 2 5 conduits. Various combinations of conduits may also be mounted.

To prevent damage to direct buried cables, install a cable shield (Stk# ) at the conduit entry and increase the quantity of cable shields shown in the Materials List by Install a conduit cover at the top end of the conduit to prevent cable damage. 9. Use DCS for ground coil application on new pole installation. 10. Always connect the metallic shields of the riser cables to the system neutral with at least a #2 stranded copper wire. Be aware that the bare and/or covered 7 strand #10 copperweld ground wire may look like stranded #2 copper wire. Never substitute the copperweld ground wire for the #2 stranded copper wire when constructing the primary neutral buss. 11. For all of Illinois and locations in Missouri where additional avian protection is needed, omit the piece of #2 bare copper wire and hot line clamp Z. Connect the #6 copper poly covered arrester wire Y directly to the fused switch connector. 12. More than one single phase riser can be ona pole.
