15 A 125 V NEMA 5-15 Y Splitter

This PAULINN splitter provides two 18-inch extension cords from a single straight-blade inlet. It is rated for 15 amps at 125 volts and uses a 2-pole, 3-wire configuration. The unit suits RV, marine, trailer and block-heater installations where a single shore-power connection must feed two devices.

Replaces single-outlet shore inlets

The integrated Y cable replaces a standard flanged inlet that only accepts one plug, letting you run two loads without adding a separate distribution box. The jump is worth it when your RV or boat has a single 15 A shore inlet but you need simultaneous power for a charger and a block heater or other accessory.

Sustained outdoor load behaviour

Nickel-coated copper contacts and a black nylon housing resist UV, impact and abrasion during continuous outdoor exposure. The weatherproof covers protect the contacts from rain, snow and dust while the plug is not in use, and the cord grip accepts 12-18 AWG conductors for a secure, long-term connection.

Questions about this item

What size mounting holes does the flanged inlet need?

The inlet requires two mounting holes; the see-through wiring block lets you align them before securing the flange.

Which step do installers most often miss when wiring the Y splitter?

Many forget to fully seat each conductor in the colour-coded crimp-lock clamps before tightening, leaving a loose connection.

When should the weatherproof covers be replaced on this shore-power inlet?

Replace the covers if the seals crack, the hinges bind, or water reaches the contacts during a visual inspection.
