Attachment to wood-sided buildings is done with either a “P” style or “Rams Horn” house hook. Attachment
to an electrical or telephone mast is done with a mast clamp.
Factors affecting the house contact are telephone location, protector location, wire runs, existing drop wire
and electrical service location.
Figure 58: Building attachment
A small amount of slack, which acts as a water drip loop, of 75-100 mm (3-4 inches) should be left and the
drop wire secured to the building with a standoff.
Wood, aluminum, vinyl, stucco, brick and stone are all examples of material used for house siding. The
difficulty in attaching to some material has led to today's standard request for conduit to be placed when the
house is being built.
1.7.3 Attaching Underground Drops
Underground drops or are installed in 3 ways.
Directly buried from a pedestal, pull box or encapsulated splice
Placed in conduit from a pedestal or pull box
Run down a pole from an aerial terminal
Developers normally provide a conduit from the foundation level to the NIB location. The builder should also
supply a #6 ground wire and Cat 5 wire from the STB or LB to the customer’s power panel. (The STB and LB
are 19 or 25 millimeter connectors that protect wire and allow it to be routed at a 90-degree angle.)
The customer must pay the cost of installing additional underground drops. The I&R technician must always
ensure that the underground drop shield is connected at the NIB and if possible, at the pedestal.
