Hi guys, my gophert cps 1620 arrived today, which operates on either 110 or 220v, switchable... but it came with a 220v plug. doh!

??? I actually no nothing about 220v, even though I've wired houses with 110. I've simply never needed to learn about it. It's 3 prong, so I'm guessing it uses two hot leads and one neutral? (no ground).

??? Is it just a matter of cutting off the plug and replacing it with a standard 3 prong 110 plug, and using the two hots as the hot and neutral, and the neutral as the ground?

thanks!

Use this typical camp ground pedestal wiring diagram for connecting up 50AMP an 30AMP connectors...

When finished with your new plug installation be sure to check the connector using this pictorial. It must read exactly as shown using a multimeter. DO NOT PLUG YOUR SHORE POWER INTO THE RECEPTACLE until this is verified otherwise it will do damage to some of your 120VAC appliances.

Be very careful dealing with these connections.

What is the NEMA designation of the plug? 6-15?

Before you go cutting off any plugs/doing any mods..........just call mfg. and inquire.

Doesn't manual have info on 110V vs 220V operation?


Is it time for your medication or mine?

Actually, I was mistaken concerning the plug. Apparently its 220v, but not u.s., sorry.

It has 3 FLAT prongs; one vertical, and two side by side on about a 30* angle from vertical... like the nema tt 33 p, but all flat.

If I can figure out how to post a pic, I will.

Looks like 240v to me. There must be a different model?
I don't see a manual with plug specifications.

There is a China 240v plug that fits that description... how about a pic?

I can download a pic of the cord onto the computer, but cannot even move it to my pics/my documents, etc.

here's the link, but that comes up empty?

When someone tells you to buy the same rig they own, listen, they might be right. When they tell you to buy a different rig then they own, really pay attention, they probably know something you don't.

220 three-wire is generally HOT, HOT and Ground (US/Canada). No neutral is it's assumed there are no 110v requirements.

The markings are as follows:

next to the top vertical prong is an E

next to the bottom left slanted prong is an L

next to the bottom right slanted prong is an N

Between the 3 reads the following:
