30A generator to 20A transfer switch

[rayl]

I have a portable backup power generator with only 30A four prong oulets. This generator is replacing an older generator with a 20A outlet that I connected to a 20A inlet box and transfer switch box in my house.

How can I connect the two? I'd like to avoid the expense of installing a new 30A inlet and switch box.

I see you can buy 30A to 20A cable adapters so I presume you can connect a 20A cable to 30A outlet?

The adapters support 5000 watt max. My new generator is 7125 peak/5700 running watts.

Can I replace the 20A plug on my cable with a 30A plug so I can plug into the generator?

the only code permissible and safe way to do this is replace the inlet AND the inside wire(depending on gauge) with a 30a inlet.

The inside wire may only be 12 gauge which is not large enough for 30a.

The adapters are obviously not rated for the power your generators puts out.

And n regards to the cable, it may not be rated for 30a either so you cant just put 30a plugs on it.

Unfortunately, there is no short cuts with this one. Do it right or dont do it at all.
