  • Post author:


In order to control the power supply between the generator and the equipment given, generator extensions are used. You need to choose the right choice in order to appreciate the valuable and different uses of extension cords!

It is really important to locate the best extension cord for generator. You are not able to specifically connect those electrical devices and machines to the socket of the generator. Extension cords were very important in those days.

So what makes an extension cable a good one? It must be flexible but solid, robust but uniform, and it is important to consider electrical problems, of course.Well, it may be difficult. But we are here to support! The best choices and purchasing guides are here.

Features to Consider in Good generator extension cord

The right extension cord is important

It is easy and fast to attach devices to a portable electric generator using extension cords.They have an instant workaround during a temporary power outage by attaching every cord-and-plug appliance (like a microwave or window Compressor) to the generator outlet panel.However, before using them, it is necessary to bear in mind the required wire gauge and length of the cords.

How to Pick the Best One?

You need to remember one specific thing when choosing an extension cord-the greater the number of amperes pulled from the plug, the thicker the copper wire in the extension cord, i.e. it can hold more power.

The American Wire Gauge (AWG) values this wire thickness, where a lower gauge number is correlated with a thicker wire with more load power. For heavier equipment than an AWG 18, an AWG 10 is thus used, mostly for on-site work.It can also be remembered that the wire’s width also plays an important role here.

Always find Outdoor cords rated for extension

In the market, Some extension cords are rated for indoor use only, while some are for outdoor use only. You certainly want an outdoor rating for use with a portable generator. In the insulation content, the power and the ends themselves, the variations are (plug & receptacle design).

Tip: My impression was that due to legislation (although the #10 wires inside might be able to handle the NEC rating) you won’t find a 10/3 extension cord with a household-style plug/outlet that lists the rating higher than 10 amps (or 25 amps with a T-blade plug).

  • For installation, do I need a professional?

You would not require a specialist to plug your extension cord if you know how to use a tool or recognise the electrical connections of your generator. In reality, most units come with an extensive guide that will direct you through the device. However, if you are inexperienced with the electric system, finding a specialist will be a smart idea. The bulk doesn’t require it.

  • It can be risky to attach extension cords?

Yes of course. Numerous protected electrical wires are within each extension cord. Heat is produced as current flows; too much heat will melt the insulation of the wires, which can cause fires or short circuits in return.

  • How could We understand while the extension cord overloads/overheats?

A very warm extension cable, a tripping circuit breaker, or uncommon noises from the attached electronics are some warning signals.

  • With a generator, may I use 2 extension cords?

Yes, if the generator outputs more than one outlet circuit, the total load can be adjusted for each circuit with an extension cord.

One of my generators is rated at 1250 watts, for example. It has many 110v traditional outlets (and a high power multi-prong outlet). I can use two 12/3 extension cords (one for each 120v outlet circuit) to provide my different appliances with electricity inside the home.

  • How to decide the appropriate cord’s length and size?

Consider this one significant detail when picking a generator power cord: the greater the number of amps, the more power the cord can handle.

 In this case, similar to a generator power cord with 20 or 30 amps, a generator power cord with 50 amps can accommodate higher wattages, so it is thicker.

 Fit the power cord of the generator and the output of your generator. Pick a 20-amp power generator cord for a 20-amp outlet and a 50-amp power generator cord for a 50-amp outlet.
