Seeking general advice in Michigan.

I am working on a sewer system for over 200 existing homes. Many of these homes are over 50 years old and I am sure there are at least a handful with substandard electrical systems.

Each of these homes will need to connect a 1/2 HP, 120V pump to their electrical system.

At the moment, the homeowners are responsible for supplying this power to the control panel. I have no doubt this is going to cause some headaches and I am looking to minimize them.

Does anyone have any suggestions that can minimize the hassle for the homeowners?

Is it possible to add a circuit outside of the house between the meter and the main circuit panel?

What's the worse case scenario for homeowner that has to add this circuit in an older electric system that hasn't been touched in 50+ years?

Thanks in advance!

The answer to this question:

Is it possible to add a circuit outside of the house between the meter and the main circuit panel?

Is NO, not this circuit.

There are only a couple of exceptions, such as Fire Alarm, Surge Protectors, that allow for what your asking, this circuit for a sewage pump does not apply.

Each homeowner will only need to provide a receptacle for the pump or contoller.

This sounds like a municipal project mandating that now these homeowners need to use these sweages pumps for some reason.

You should check with the local electrical inspector for guidance, and have the engineer for the sewer project issue specifications to the homeowners.

The inspector can help with one thing comes to mind, new outlets in basements now need to be GFI protected. Asking the inspector about this can help with waiving this code. I would think that a sewage pump should not be GFI protected.

Each homeowner is responsible for the condition of their electrical system.

Adding a 1/2 HP 120 volt motor is not a big deal. Code calls for 9.8 amps.

Each owner needs to be provided with clear specifications of what to have installed, how to protect it, and location of the circuit/outlet.

Any existing substandard conditions will be up to them to repair/upgrade. etc.
