A generator owner's question about connecting the equipment to their home raised safety concerns after Reddit commenters spotted conflicting model information and wiring documentation.
What initially looked like a single white wire attached to a grounding screw turned out to be two, leaving an important connection question unresolved.
Here's what to know
In a Reddit discussion, the owner described plans to connect a generator to a home subpanel using an interlock kit. The proposed preparation step was to disconnect an apparent neutral-to-frame bond on the unit, which they identified as model SUA12000EP. They wanted to know whether that change would make it ready for the home connection.
"Can I just remove the white wire from the ground screw, properly tape and secure, and it be ready for the house setup?" the original poster asked.
To verify that the outlets no longer had a neutral-to-ground connection, a commenter recommended checking with a digital multimeter. That advice accompanied an initial agreement with the owner's proposed change.
That response, however, did not establish that the complete home connection would be safe. Further replies raised questions about the generator's model and its internal wiring.

More background
Two model numbers were now in play: the SUA12000EP named by the owner and the SUA12000EC that another commenter said appeared on the photographed label. The commenter, who had examined the documentation, noted that the label also designated the generator as having a bonded neutral.
The written descriptions and wiring diagrams did not agree: Both models' diagrams appeared to depict a floating neutral, with no neutral-to-frame bond.
One white conductor ran to the 50-amp outlet; another ran to the main wiring harness. The owner reported finding both attached to the ground screw after reopening the control panel, rather than the single wire that had initially appeared.
That discovery prompted another warning: Separating the wires could interrupt a connection the receptacles need.
"All about safety and confirming," the commenter wrote.
