ABYC Standards
The construction of insulated cables and
conductors shall conform with the requirements of: 11.16.1.2.2.1. UL 1426,
Cables for Boats…”11.16.1.2.2.”
"Conductors shall be at least 16 AWG. EXCEPTIONS: 1. 18 AWG
conductors may be used if included with other conductors in a sheath and
do not extend more than 30 inches (760mm) outside the sheath.”
11.16.1.1.2.
"Conductors shall have a minimum rating of 600 volts.” 11.16.1.3.3.
“The temperature rating of conductors and flexible cords shall be at
least 140ºF (60ºC) dry.” 11.16.1.3.1.
"In engine spaces, 11.16.1.3.4.1. the
insulation shall be oil resistant, and 11.16.1.3.4.2. the temperature
rating shall be at least 167ºF (75ºC) dry.” 11.16.1.3.4.
"Minimum surface marking of the individual conductors and their
jackets shall include: 11.16.1.1.1.1. type/style, 11.16.1.1.1.2. voltage,
11.16.1.1.1.3. wire size, and 11.16.1.1.1.4. temperature rating, dry.”
11.16.1.1.1.
"All conductors and flexible cords shall meet the flame retardant and
moisture resistant requirements of UL 83,Thermoplastic-Insulated Wires and
Cables.” 11.16.1.3.5.
"Conductors used for panelboard or switchboard main feeders, bilge
blowers, electronic equipment, navigation lights, and other circuits where
voltage drop must be kept to a minimum, shall be sized for a voltage drop
not to exceed three percent”. (See Table B)
Conductors used for lighting, other than navigation lights, and other
circuits where voltage drop is not critical, shall be sized for a voltage
drop not to exceed 10 percent.” 11.16.1.2.7. (See Table C)
"When AC and DC conductors are run together, the AC conductors shall
be sheathed, bundled, or otherwise kept separate from the DC
conductors.” 11.16.4.1.5.
"Wiring shall be installed in a manner that will avoid magnetic loops
in the area of the compass and magnetically sensitive devices. Direct
current wires that may create magnetic fields in this area shall run in
twisted pairs.” 11.16.4.2.1.
"Current-carrying conductors shall be
routed as high as practicable above the bilge water level and other areas
where water may accumulate. If conductors must be routed in the bilge or
other areas where water may accumulate, the connections shall be
watertight.”11.16.4.1.6.
"Loom used to cover conductors shall be self-extinguishing. The base
product (or resin) shall be classified as V-2 or better, in accordance
with UL 94, Tests For Flammability Of Plastic Materials.” 11.16.4.1.9.
"Conductors shall be supported throughout their length or shall be
secured at least every 18 inches (455mm) by one of the following
methods:” 11.16.4.1.10.
"By means of non-metallic clamps sized to hold the conductors firmly
in place. …The material shall be resistant to oil, gasoline, and water
and shall not break or crack within a temperature range of -34°C (30°F)
to 121°C (250°F);” 11.16.4.1.10.1.
"By means of metal clamps lined with an insulating material resistant
to the effects of oil, gasoline, and water.” 11.16.4.1.10.3.
"Terminal connectors shall be the ring or captive spade types.”
11.16.3.4.
"Twist on connectors, i.e., wire nuts, shall not be used.”
11.16.3.6.
"Ring and captive spade type terminal connectors shall be the same
nominal size as the stud.” 11.16.4.1.12.
"Solder shall not be the sole means of mechanical connection in any
circuit.”11.16.3.7.
"Solderless crimp on connectors shall be attached with the type of
crimping tools designed for the connector used, and that will produce a
connection meeting the requirements of E-11.16.3.3.” 11.16.3.8.
"The shanks of terminals shall be protected against accidental
shorting by the use of insulation barriers or sleeves, except for those
used in grounding systems” 11.16.3.9.
"Conductors that may be exposed to physical damage shall be protected
by self-draining; loom, conduit, tape, raceways, or other equivalent
protection.” 11.16.4.1.8.
