Important: Always refer to your generator owner's manual to confirm the correct part number and plug configuration before purchase. Do not rely solely on product images to determine compatibility. Incorrect cord selection may result in equipment damage or safety hazards.

Product Overview

This Generac 25-foot generator power cord is built for heavy-duty residential and jobsite use, connecting your generator to a transfer switch, power inlet box, or other 240V load center. Constructed with 6-gauge rubber-jacketed conductor wire, it supports up to 12,500 watts at 240V and is rated for 50 amps — making it suitable for large standby and portable generators. The cord features NEMA L14-30 4-prong twist-lock male and female connectors for a secure, vibration-resistant connection, along with a NEMA L14-50 straight-blade generator plug that connects to generators equipped with straight-blade (L14-50) outlets. The flexible rubber jacket maintains pliability in cold outdoor conditions and resists abrasion, oil, and UV exposure for long service life.

Key Benefits

Heavy-Gauge 6 AWG Wire — Up to 12,500W: 6-gauge copper conductors handle up to 12,500 watts of continuous load at 240V with minimal voltage drop across the full 25-foot run — sized for large portable or standby generators operating at or near full capacity.

L14-30 Twist-Lock Security: NEMA L14-30 locking male and female connectors twist and lock into place, preventing accidental disconnection from vibration or cord tension during extended generator operation — a critical safety feature for outdoor and jobsite use.

L14-50 Straight-Blade Generator Plug: The 50-amp straight-blade (L14-50) generator-end plug connects directly to generators equipped with straight-blade outlets, eliminating the need for adapters and providing a clean, direct connection to the power source.

Flexible Rubber Jacket Construction: The rubber outer jacket remains flexible in cold weather conditions, resists cracking, abrasion, oil, and UV degradation — making this cord well-suited for permanent outdoor installation or repeated seasonal use.

25-Foot Reach for Flexible Placement: The 25-foot length provides sufficient distance to position your generator safely away from doors, windows, and vents as required by code, while still reaching your home's power inlet box or transfer switch without extension.

How It Works

This cord serves as the physical power link between a portable generator and your home's power inlet box or manual transfer switch. The L14-50 straight-blade plug connects to the generator's outlet, and the L14-30 twist-lock female end connects to the power inlet box mounted on your home's exterior. Once connected and the transfer switch is engaged, generator power flows through the cord into the home's electrical panel to supply selected circuits.

Generator-End Connection (L14-50 Plug): The straight-blade L14-50 50A plug inserts directly into the generator's receptacle outlet. Always ensure the generator is off and in a safe state before making or breaking this connection.

Load-End Connection (L14-30 Twist-Lock): The NEMA L14-30 female twist-lock connector at the load end secures to your power inlet box or transfer switch receptacle. Align the prongs, insert, and rotate to lock — creating a firm, pull-resistant connection that won't loosen under vibration.

Safe Generator Placement: The 25-foot cord length allows the generator to be placed at a safe distance from the home in compliance with NFPA and local codes requiring a minimum 20-foot clearance from openings — never operate a generator indoors or in an attached garage.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
