Generator L14-20 Power Cord


I have a 5000-watt generator (6250 w surge) with an L14-20 connector. I want to purchase a L14-20 power cord with 4 outlets to run two 1/3 hp sump pumps, a refigerator and a freezer. Should I buy the L14-20 cord that has 4-15 amp connections or 4-20amp connections.

The 15A one will be fine. Out of curiosity, why not just plug your individual devices directly into the generator?

That is an option, but only because the single L14-20 connection is more water tight for outdoors and then only one line has to be exposed to weather that can be run into the garage where the extension cords can be connected in a dry environment. Is there a problem running those items that usually run off of 15-amp circuits on the 20-amp cord.

This is a case where I'd get the 20A just in case you need it later on for heavier loads. It's only an extension cord.

The reason why I suggested the 15A model is because it's only a 20A twistlock that he is splitting up 4 ways (two ways per leg).

There is no harm in using the 20A model, but I just don't think you will find any advantage to it. I assume it costs more money.

That was my thought as well on the 20amp cord, just in case I needed it for some appliance or equipment that could not use the 15amp outlets. I have four 15-amp outlets on the generator plus the 240V connector. I thought it would make sense to have the L14-20 connector with 20amp circuits. I just wanted to know if I could run the sump pumps and other 15amp applicances off the 20amp cord without any issue, rather than buy the L14-20 that has the 4 more 15amp connectors.

The L14-20 cord with four 20-amp connectors is actually cheaper than the one with the four 15-amp outlets, neither one was easy to find online, I just figured like Speedy said, if I buy the cord with 20 amp outlets that I can still use for 15-amp appliances then I will have the 20amp adapter if needed in the future for any items using heavier loads. Thanks guys for your input.

I've never seen something with a 20A plug on it other than one of those huge printers in an office building once. but if the adapter with the 20A receptacles is cheaper, go for it.
