Location: Columbia, KY | We were camping this weekend and a friend has some type of little sensor device that plugs into the trailer to test for proper grounding. It showed my trailer wasn't grounded properly when I was using 2 Honda EU 2000's to power it, so in theory if there was a short somewhere this could be a real problem.
Suggestions or comments?
thanks! |

Location: Miami, FL | My Yamaha (EF3000) does the same thing - since 2007. Never worried about it. Only when connected to outside power (city) does my outlet monitor ("sensor") display complete electrical (including ground). |

Location: Belchertown MA | My Honda 2000 has always been that way too. Something to do with being an inverter and sine waves ?? Been using it for 10+ years with no problems,2 different trailers, other friends as well |

| Your generator has a means of an external ground wire that should be connected to a grounding rod. People have been killed using power generators without beiing grounded. All of us have been lucky using the generator without a ground.

Location: Vermont | Q. What are the grounding requirements for a portable generator?
A. According to 250.34(A), the frame of a portable generator isn't required to be grounded (connected to the earth) if: - The generator only supplies equipment or receptacles mounted on the generator, and
- The metal parts of the generator and the receptacle grounding terminal are connected to the generator frame.
According to 250.34(B), the frame of a vehicle-mounted generator isn't required to be grounded (connected to the earth) if: - The generator frame is bonded to the vehicle frame,
- The generator only supplies equipment or receptacles mounted on the vehicle or generator, and
- The metal parts of the generator and the receptacle grounding terminal are connected to the generator frame.
A portable or vehicle-mounted generator used as a separately derived system to supply equipment or receptacles mounted on the vehicle or generator must have the neutral conductor connected to the generator frame [250.34(C)]. Note: A portable or vehicle-mounted generator supplying fixed wiring for a premises must be grounded (connected to the earth) and bonded in accordance with 250.30 for separately derived systems and 250.35 for non-separately derived systems.

Do these 2 factors apply to the typical Honda/Yamaha invertors? |

There's a lug on the control panel of these inverter gensets to ground the equipment to earth..... I got two Yamaha inverter generators, both have ground lugs and it's all explained in the owners/operators manual.
