Limitations of Some Generator Receptacles
[ad#block]Generator Question: I have an older Coleman generator, Coleman Maxa 5000 er plus Model# pm0525302.02, and it has one duplex 120volt 20 amp receptacle and one 240 volt 20amp type 6-15R receptacle.
- Can I change the 240volt into something useful like one or two more 120 volt receptacles.
- I got this generator for free and it runs great, but if there is a power outage the single 120volt won’t feed much.
This Home Generator Question came from: Eric, a Homeowner from Norwalk, Connecticut.
Dave’s Reply:
Thanks for your home generator question Eric.
Wiring a Generator Receptacle
Application: Generator Receptacle Connections.
Skill Level: Advanced -Not recommended for Homeowners, best performed by a Licensed Electrical Contractor.
Tools Required: Electricians pouch of hand tools.
Estimated Time: Depends on the type and size of the generator output, the specific receptacle, and the available access to the project area.
Note: Generator power should always be wired through an approved transfer switch or circuit interlock device. Any part of the home electrical system must NEVER be back-fed using a cheater cord. Back-feeding is extremely hazardous for the home, the occupants and the electric utility company repairmen.
Important: Installing a generator and transfer switch must be well thought out and performed with a permit with all work being inspected.
Generator Hookup and Receptacle Configurations
- The generator receptacle configurations are specific to the type of generator that you have.
- The generator receptacle cannot be altered.
- The NEMA 6-15r does not have a neutral which is required for the additional 120 volt receptacles that you would like to add.

I have a Coleman Maxa 5000 ER Extended run electric Generator and need the wiring schematic for the receptacles. Seems I have looked everywhere. Can anyone on here help me with this problem by chance? Thanks
Hi Wayne,
Wiring a L14-20 Outlet for a 5000 Watt Generator
The Coleman Powermate 5000ER has a 4 Wire, 120/240 Volt, 20 Amp, Twistlock Receptacle.
The 240 volt lead wires connect to terminals X and Y.
The neutral wire attaches to the silver terminal screw.
The ground wire attaches to the green screw terminal with the ground designation.
I hope this helps,
Dave
I had to replace the 240v receptacle on my Coleman Powermate MAXA 5000ER Generator. While doing so I lost track of where a couple of wires went. I have a pretty good idea where they go but just not a 100% and would hate to burn up a perfectly good generator. Could you supply my with a Diagram of where the wires go?
The generator is a Coleman model#PM0525202.02
