Has anyone pulled apart this Honda adapter



to ground the neutral like in this plug

Are you doing this to bypass an inhouse surge protector?

Instead of the copper consider a 100k ohm 1/2 watt resistor. It will work without presenting any real power to the ground. I have that orange adapter but have never pulled it apart.

I replaced the chassis grounded, ground pin duplex outlet with a hospital grade floating ground (not tied to the outlet mounting tabs) orange duplex, and tied ground and neutral together at the power source. Doesn't matter whats plugged in, it all sees a bonded neutral/ ground, just like a residential install.

.

Since a "portable" generator can be used on many different applications (like RVs, direct power tools, stick home generator panel, etc. etc.), I would simply leave the generator output outlets "as is". Especially if the generator is under warranty. re: Don't modify the generator to void its warranty.

I would simply buy 24 inch long thick 12 gauge wire (for 110/120V - 20A). I would then attached a male 3-prong male at one end. And, attach 3-hole female on its other end. Within the male or female end (depending on physical available space in each connector), I would bond white and bare wires together. Thus, creating a special "bonded" short adapter cable. If I use the generator on an application that needs bonded power source, I would use this special 24" long cord. If NO bonded power source is needed, I would then connect the item directly to the generator socket.

This works for me...

Yes that is the reason. I just like the way the 30amp male plug on the shore power cord plugs into the orange adapter. (good and solid) Don't really want to have a bunch of adapter cords laying around in the rain and dirt and such. I can always shut the EMS off when running the genny. I am not sure I really need the EMS with the genny anyway. Just wondered if anyone has ever pulled that orange adapter apart.

Have you actually done this?

Yes. I did this with the advice of an electrical engineer to enable my Nissan LEAF to charge from my generator if the need should arise. LEAF has a similar check for ground as the Progressive EMS. And yes it works.

I used a generic three prong replacement plug from Home Depot. You could probably just put the resistor inside the generator. It will not affect anything plugged in. It will not pass enough amps to feel the 60vac to ground as the copper could do.

It is a 100,000 ohm resistor. 1/2 watt or more.

That adapter doesn’t have the ground connected to the neutral. But you can use a meter to confirm that without opening it. Not to open a can of worms, but if that adapter doesn’t have a CSA approval on it, it is illegal to use in Canada. Also the adapter won’t work with some generators with configured with a split phase output.

DH made a special ground connector to use when running the fifth wheel off our generator. Fifth wheel has an in house surge protector.
