Plugs & Connectors

Plugs & Connectors keep power flowing safely and efficiently on jobsites, in workshops, and around the home. This category covers replacement plug ends, cord caps, in-line connectors, adapters, and specialty power interfaces designed to match specific amperage, voltage, and environment needs. Choose from straight-blade and twist-lock NEMA devices, IEC power connectors for equipment, weather-resistant and watertight IP-rated styles for outdoor use, and heavy-duty industrial plugs built to handle frequent mating cycles and vibration.

Key benefits include reliable electrical contact, strain relief that protects conductors, and clear polarity and grounding that reduce tripped breakers and heat buildup. Upgrading worn plug ends on extension cords or tools improves performance and helps meet safety standards. Look for UL or CSA listings, rugged thermoplastic or rubber housings, nickel-plated brass blades, and cord grips sized to your cable’s outer diameter.

How to select the right plug or connector:
- Match plug pattern and rating: 125V vs 250V, 15A, 20A, 30A; confirm NEMA configuration (5-15, 5-20, L5-30, etc.).
- Size for wire gauge and number of conductors; verify stranded vs solid compatibility.
- Choose locking or non-locking based on movement, vibration, or generator use.
- For outdoor or wet locations, pick IP65–IP67 or marine-grade options with gaskets.
- Consider clear-body, lighted ends for quick power checks.

Installation tips: disconnect power, strip conductors to spec, maintain color coding (green/ground, white/neutral, black/hot), torque terminals per manufacturer, and test with a receptacle tester. Inspect periodically for heat discoloration, cracks, or loose clamps.

Popular applications include generator cords, RV hookups, temporary power distribution, welders, compressors, and server or AV equipment using IEC C13/C19. Explore plug adapters, pigtails, cord-connectors, and replacement ends to extend cable life and keep your electrical plugs and connectors reliable, safe, and ready for work. Stock multiples to minimize downtime and standardize your fleet; labeling helps.
