I just bought a Honda Generator Model# EG 6500CL, with the setting on 110V only, I want to deliver the maximum rated current of 45.8V to one load. There are 3 receptacles available, 2 at 20A, 1 at 30A and all the outputs are in phase and from the same winding. The Operation Manual states you cannot exceed receptacle current limits. Can I parallel 2 or 3 receptacles to achieve the maximum current rating of 45.8A? Honda Canada would not give a definitive answer.

  • \$\begingroup\$ This site is not for providing directions explaining how to use products. I am voting to close the question. Connecting receptacles in parallel will not assure that the current will be properly divided among the receptacles. Parallel operation is not a proper use of the receptacles and will invalidate the UL listing. The circuit breakers will probably prevent damage, but that does not mean that what you propose is proper use. \$\endgroup\$ – Charles Cowie Dec 28 '18 at 20:23
  • \$\begingroup\$ Yes you could run into trouble if they have different fuse protection values. But if there is only a common Circuit breaker it may be ok. ... as long as you construct the branch cable correctly and keep short or use AWG to minimize losses with suitable endpoint connection. \$\endgroup\$ – Sunnyskyguy EE75 Dec 28 '18 at 20:41

    \$\begingroup\$ If you parallel two circuits then if you unplug one lead its pins will be live and not touch-proof. Bad idea for this and the other reasons listed. \$\endgroup\$ – Transistor Dec 28 '18 at 21:21
  • \$\begingroup\$ @Transistor You added something essential. I wrote about it in my answer. Unfortunately nothing stops some people as long as they stay alive. I have seen custom 230VAC extension cords where a male plug is in both ends. \$\endgroup\$ – user287001 Dec 29 '18 at 2:36

Don't do it! As commented already, the current can be too non-uniformly distributed due different resistances. In addition:

  • Have you already checked that the outputs really come from the same winding (=in parallel connected windings) in the single voltage mode? The actual generator in the machine must be extremely precisely made if there's parallel windings.

  • If yes, then how you can be sure that all output connectors to your single load stay connected and none is ever reversed?

  • Have you checked what happens if the machine is in 2 voltage mode and the outputs still are in parallel?

If one or two pops out or get damaged, something can get overheated without warning. Reversing = Short circuit.

The manufacturer would never allow your planned connection because they should pay your burned house if they allowed the connection and you left 2 outputs disconnected.

User Transistor had added something essential: Unplugged parallel connector has full voltage. => If the manufacturer allowed your connection, they should also prepare to pay the possible funerals.

  • \$\begingroup\$ It sounds like there are too many variables trying to combine the the different maximum outputs. I could overload the output of one or more receptacles. The Operational Manual does have a schematic drawing showing a common winding with the 3 receptacles in parallel. I will divide the load to keep the output of the 3 receptacles within current limits. \$\endgroup\$ – araeiabc Dec 28 '18 at 21:10
