EXAMPLE OF ANTENNA GROUNDING ACCORDING TO NATIONAL
ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810- "RADIO
AND TELEVISION EQUIPMENT"
POWER SERVICE GROUNDING
ELECTRODE SVSTEM
BONDING JUMPE
OPTIONAL ANTENNA GROUNDING ELECTRODE
a. Use No. 10 AWG (5.3 mmz) copper. No. 8 AWG (8.4 mmz) aluminum. No. 17 AWG
(1.0 mmz) copper-clad steel or bronze wire, or larger, as a ground wire.
b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced
from 4-6 feet (1.22-1.83 m) apart.
c. Mount antenna discharge unit as close as possible to where lead-in enters house.
d. Use lumper wire not smaller than No. 6 AWG (13.3 mmz) copper, or the equivalent,
when a separate antenna-grounding electrode is used. See NEC Section 810-21 (j).
Carts and Stands - The appliance should be
used only with a cart or stand that is recom-
mended by the manufacturer.
An appliance and cart combination should be
moved with care. Quick stops, excessive force,
and uneven surfaces may cause the appliance
and cart combination to overturn.
PORTABLE CART WARNING
Pour prevenir les chocs electriques ne pas
utiliser cette fiche polarisee avec un prolon-
gateur, une prise de courant ou une autre sortie
de courant, sauf si les lames peuvent etre
inserees a fond sans en laisser aucune partie a
decouvert.
17 Grounding or Polarization - Precautions should
be taken so the grounding or polarization
means of the component are not defeated.
Section 810 of the National Electrical Code,
ANSI/NFPANo. 70-1984, provides informa-
tion with respect to proper grounding of the
mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna-
discha'rge unit, connection to grounding
electrodes, and requirements for the grounding
electrode.
