Int'l Dock SPC-21-2T-326 Shore Power Pedestal - 30A + 20A GFCI

The International Dock SPC-21-2T-326 is a 21-inch marina shore power pedestal designed for residential docks, smaller marina slips, and single-vessel installations where you need one 30-amp boat shore power outlet plus a 20-amp GFCI duplex for general-use power. For dock owners building or upgrading their shore power infrastructure, the SPC-21-2T-326 delivers professional marina-grade construction at a price point appropriate for residential and small commercial installations.

What 'SPC-21-2T-326' means in the model number. International Dock uses a structured part numbering system: SPC = Shore Power Cabinet, 21 = pedestal height (21 inches), 2T = number of major receptacles (2 total - the 30A twist-lock and the 20A GFCI duplex), 326 = the specific receptacle configuration code (30A twist-lock plus 20A GFCI). The pedestal is part of a larger product family with various configurations (different heights, more receptacles, optional meter / cable / phone, etc.) - the SPC-21-2T-326 is the basic 21-inch dual-receptacle variant without the optional accessories.

The two receptacles - what they're for. UPPER RIGHT: 30 Amp 125V twist-lock receptacle - the standard marine shore power inlet that connects to your boat's 30-amp shore power cord. Twist-lock design prevents accidental disconnection from wave motion, wind, or someone tripping over the cord. 30 amps at 125V is enough for typical boats up to 35-40 feet running normal AC loads (battery charger, refrigeration, AC if running shore-powered, water heater, lights, electronics). For larger boats needing 50A service, step up to the SPC-21-2T-526 (or similar) variant with the 50A receptacle. UPPER LEFT: 20 Amp GFCI Duplex receptacle - the standard NEMA 5-20 duplex outlet you'd see in a home or commercial building, with GFCI protection for safety in the wet marina environment. Useful for: dockside power tools (vacuum, pressure washer, drill), accessory power (TV / radio / charger), holiday lighting, and any 120V appliance under 20 amps. GFCI protection trips immediately on ground fault - critical safety feature in the wet marine environment where the risk of electrical shock is meaningful.

Direct-feed power distribution. The pedestal's internal power distribution box is a direct-feed design accepting up to 2/0 marine-grade tinned wire from the marina's main distribution system. Direct-feed means the main feed wires terminate directly to the receptacle circuit breakers without an intermediate junction box - cleaner installation, fewer connection points, and better long-term electrical reliability. The 2/0 maximum wire size handles the high-amperage main feeds typical of marina power distribution (50A or 100A feeds carrying the dual-circuit pedestal load). For installations with smaller marina feeds, smaller wire sizes also fit the distribution box.

Cone-top design - rain and debris management. The cone top sheds rain water (no standing water pooling on top of the pedestal that would eventually cause corrosion or freeze damage in winter climates) and discourages debris accumulation (leaves, twigs, bird droppings). The slight cone angle is steep enough to drain water but not so steep that it looks aggressive on the dock aesthetic - functional design that blends into marina infrastructure.

Powder-coated white finish inside and outside. The pedestal casing is finished in powder-coated white paint on both interior and exterior surfaces - much more durable than typical liquid paint, with better adhesion to the metal substrate, better UV resistance, and better resistance to chipping and impact. The white color matches typical marina aesthetics and reflects solar heat (helps keep internal electrical components cooler in summer sun). Coating inside and outside is critical for long-term marine service - many cheaper pedestals don't coat both sides - they coat only the exterior, leaving the interior to corrode from condensation and moisture intrusion.

Stainless steel fasteners with nylon washers. All external fasteners are stainless steel - immune to corrosion in the marine environment. Nylon washers between the stainless fasteners and the powder-coated casing serve two purposes: (1) prevent galvanic corrosion between dissimilar metals (stainless steel and the underlying aluminum / steel casing), and (2) prevent fastener loosening under thermal cycling (the nylon's slight elasticity maintains preload as the metal expands and contracts with temperature changes). Small detail that matters significantly for long-term reliability in outdoor marina service.

PL-9 fluorescent light with photocell. The integrated lighting fixture uses a PL-9 fluorescent bulb (9-watt compact fluorescent) controlled by a photocell that automatically switches the light on at dusk and off at dawn - no manual operation required. The light provides ambient dock illumination useful for: helping boaters find their slip in low-light conditions, providing safety lighting around the shore power pedestal where electrical connections need to be made, and adding to the overall marina lighting infrastructure. The PL-9 is the standard marina pedestal lighting choice - affordable, long service life, energy efficient, and bulb replacements are widely available. For owners wanting LED upgrades, retrofit LED bulbs in the PL-9 form factor are available from electrical suppliers.

Two mounting bracket options included. ROUND bracket: for mounting the pedestal to round dock pilings (typical of residential docks with round wood pilings). The round bracket clamps around the piling and the pedestal bolts to the bracket. FLAT bracket: for mounting to flat surfaces like fixed dock edges, finger pier corners, square concrete pilings, or wall surfaces. Both brackets are included with the pedestal - choose the appropriate one for your specific mounting location. The dual-bracket inclusion eliminates the need to specify mounting style at order time and accommodates installation site changes between order and install.

Hubbell Thermo-plastic receptacle covers. The receptacle covers are Hubbell Thermo-plastic - the premium spring-loaded weather-resistant covers used in marine and outdoor electrical installations. Properties: resistant to UV degradation (won't yellow or crack over years of sun exposure), resistant to saltwater (won't corrode in marine environments), impact resistant (won't crack from accidental hits), and properly sealed when closed (keeps water out of the receptacles when not in use). Standard equipment in commercial marina installations.

15-year structural warranty. International Dock provides a 15-year unconditional warranty on the structural integrity of the pedestal casing - among the longest warranties in the marina shore power pedestal market. The warranty covers the casing structure (the metal cabinet itself), the powder-coat finish (against peeling or premature failure), and the structural welds. Electrical components (circuit breakers, receptacles, lighting) carry their own component-specific warranties from the original equipment manufacturers (Hubbell, etc.). The 15-year structural warranty is meaningful evidence of the pedestal's expected service life - International Dock wouldn't offer the long warranty without confidence in the build quality.

What's isn't included. The SPC-21-2T-326 is a basic 21-inch dual-receptacle pedestal - the included receptacles are 30A 125V twist-lock and 20A GFCI duplex. isn't included: cable TV outlet, phone / data outlet, electrical meter (for sub-metering individual slips), additional lower receptacles, dock water supply hookup, or fire extinguisher cabinet. For installations needing these features, International Dock makes larger pedestals (taller, more receptacle positions) with the additional outlets - check their product catalog for the variant matching your needs.

Install considerations. Plan for a licensed electrician install - marina shore power installations involve high-amperage AC wiring with significant safety implications. Tasks: mount the pedestal to the dock piling or flat surface using the appropriate included bracket (round or flat) and stainless hardware. Run the main feed cable from the marina's electrical distribution system to the pedestal's power distribution box (2/0 marine-grade tinned cable max). Verify proper grounding (the pedestal must be properly grounded back to the marina's main panel - critical for GFCI operation and safety). Test the GFCI receptacle function with the integrated test / reset buttons. Verify the photocell operation by covering the photocell during testing. Total install: typically 4-8 hours for a licensed marina electrician, depending on site conditions and main feed cable run length.
