I recently purchased a generator that has a 4 prong 30 amp outlet. I want to connect it to a 20 amp transfer switch, also 4 prong. I have 10 gauge wire, and bought the male and female ends. The problem (maybe) is that I bought 20 amp male and female ends. Should I have bought 30 amp?

Thank you.

Yep... but why didn't you get a 30 amp transfer switch? Would have made this a bit simpler, don't you think? What kind of switch did you buy?

We have simpler solutions for you: Generator InterLock Kit

You did get a generator input connector (male) that's mounted on the outside of your house.

I bought a 20 amp switch, but am cancelling that order and buying a 30 amp.

And back to KISS's question. How are you plugging it in... do you have an outside connector wired to the switch, or is it the built in kind?

Running a short 10 gauge cord through a small hole in wall from switch to generator

Can I ask what 30 amp transfer switch you plan on getting? Reliance makes a kit that includes the cord, and I believe it's about $279 at Lowe's... you may find it for less online or locally.

It is a reliant 30 amp, 6 circuit. I have to make the cord, because the hole in the wall leading to the basement is only large enough for the cord, and not the ends. There is not enough room to mount an outlet either.

Cord cannot be passed through a structure.

This is an existing cord that the previous owners of the house used to run an air conditioner in the garage.

Still does not make it right.

Thank you.

Listen to TK. An extension cord is for temporary use only. Buy the male connector and install it properly. Extension cords, and that is what it is can't be permanently installed. Just mount the connector where the hole is and wire it with an approved wiring method, cable, conduit... whatever. Be safe.
