Hi,
My question is simple, I have to install an injector pump in my basement crawl, and I will be doing so to code. However, in terms of getting power to the injector pump I wanted to hear what people normally do. I currently have a sump pump within the vicinity of where I will be installing the sewage injector pump, and it has its own dedicated outlet (home run to panel). My question is will that outlet be sufficient to run a sump pump and injector pump or should I make another home run to panel and dedicate the injector pit/pump to its own breaker. Keep in mind, I have an older panel, I believe they call them 'pushmatics' and I am aware of the problems associated with getting parts/service on these relics. Please don't be judgemental in your RE: just tell me what a liscened plumber would do when installing these things.

Thanks

A licenesed plumber would have a licensed electrician run a dedicated wire to the ejector pump.

Hi Chip,
Sounds like the real concern is about the capacity of the outlet being appropriate to power two pumps...
The maximum load that I would recommend on any 15 amp, 120V outlet is 12 amps, the maximum load on a 20 amp, 120V outlet is 16 amps...
The pumps you have should have the rated running current or full load current and voltage listed on them...
If both add up to less than 80% of the circuit breaker size you can power them both. If more than 80% or you would prefer to play it safe... put them on their own circuits.
ITE Pushmatic breakers may still be available just not easy to find.

Also, I would not allow a plumber to do electrical work unless of course he is licensed... filing for permits and inspections is not only required in the US for this work but I strongly recommend it

Be safe...

A slight difference of opinion.

On a dedicated circuit, a single outlet and receptacle of either of 15 or 20 amps the maximum amperage is that of the overcurrent protection device (the breaker).

It becomes 12 or 16 amps when the circuit serves multiple receptacles.

Again, it really depends on the available power at the pneoard and the safety of the panelboard.

As previosly mentioned, I also would not recommend placing both devices on the same circuit.

Without knowing the details of each motor, one can only guess.

We need to know the horsepower of each motor.

Motor circuits are sized differently than standard receptacle circuits.

3/4 hp sump pit, (runs more so when it is raining) and the ejector pump is also 3/4hp. Lots of info guys, thanks for all the help. Decided to run a home run to panel, although I should probably upgrade to a new 200 amp svc. Down stairs, as I know them pushmatics are outrageous to replace the pushmatic breakers or to even add one. 50$ for a 15amp one!
