1. All materials and equipment used in the installation will
conform to Underwriter’s Laboratories standards and must be designed for
intended Marina use. Materials and equipment should be standard products
of a manufacturer regularly engaged in the manufacture of such products.
Such products shall meet the design standards for the specific
application and should have been in satisfactory use for a period of two
years in a like application. Exceptions to ‘use period’ may be
authorized by the Engineer where the material satisfactorily meets a
general use criteria or adequate laboratory testing has been completed.
2. The Power Outlet Box shall be UL listed as a complete
assembly.
3. Electrical wiring will consist of insulated stranded copper type
THHN/MTW conductors rated for service at 90°C or THHW/MTW VW-1 Boat
Cable rated for 105°C. Non-wire conductors will be tin plated copper
and/or aluminum Lugs.
4. The Power Outlet Box shall be molded of polycarbonate or
polyvinyl chloride polymer and all body parts shall be corrosion, impact
and UV resistant capable of withstanding high humidity and caustic
environments.
5. Color shall be permanent molded in white to resist showing
scratches and chips and all external surfaces shall also be painted to
further resist the effects of aging.
6. The Power Outlet Box shall attach to post or railing with an
internal fastening system to eliminate unsightly through bolts and to
minimize removal by vandals.
7. The Power Outlet Box shall be constructed so that it may be
installed (both physical mounting and utility connections) without
mechanical disassembly of internal parts.
8. The Power Outlet Box shall have a hinged cover that will
support itself in the open position, i.e. with hands off.
9. All external screw fasteners that require removal to gain
access for any installation, maintenance or modification must thread
into a brass insert, and not rely on threads holding in a plastic part.
10. It shall be possible to change or maintain receptacles and
circuit breakers by exchanging snap in panels as opposed to rewiring
individual components.
11. Installation is to be in accordance with local codes and
approved by local electrical inspector.
1. Receptacles shall be corrosion resistant, grounding type,
conforming to NFPA Volume 303 Chapter 3, Section 3.13.
2. Receptacles shall be mounted at approximately 60 degrees down
from the horizontal.
3. Each receptacle shall be protected by a thermal magnetic
circuit breaker that is ambient temperature sensitive.
4. Receptacles and their respective circuit breakers are to be
assembled together on a panel that can be removed and inserted into the
Power Outlet Box with a plug connection mechanism.
5. All receptacles shall be covered by a hinged door that
prevents water from dripping on the plug, receptacles and circuit
breakers. These doors must latch closed with and without plugs and power
cords attached, and must be lockable with a padlock with a 0.200” dia.
