Wiring sub panel from 100amp pushmatic breaker

Good morning Ladies and Gentlemen,

I have an older home whose older 100amp pushmatic breaker is pretty much maxed out.

I want to add a 240v light controller and 230v? air conditioner to my homes breaker. For the light controller it says its input power 30 amps and output power 20 amps. Can I safely hook this up to a 20 amp breaker?

Eventually I will have a new 200amp line put into my house from the city with inspections etc.

But for the very short time being can I get a 60 amp breaker and safely run a sub panel to power a dryer 30 amp, 20 amp air conditioner, and 20?amp for the light controller? My dryer is hooked up to a 30 amp now. Could it be hooked up to a 20 amp breaker?

Thanks for your help!

I also have pictures of the pushmatic breaker and wiring etc. But I need some help with how to post them
You cannot have a lighting circuit more than 125V in a dwelling unit. What you are proposing is not acceptable by the NEC

The dryer needs a 30 amp circuit.

It sounds like your service has passed it's usable lifespan. Those breakers will not be cheap. Put the money into the new panel.

Why not? Its safer and more efficient to run on 240.

Looks like Im going to just unplug my dryer for the summer. Ill hook up the light controller to a 30 amp breaker and run conduit up the wall and upstairs to the unit.

Any tips?
It's clac'd at 30 amps yah dirty doper ;) You should definitely get an electrician to do any work done for profit.
I always assumed 240v was not allowed for residential lighting because of safety. What makes you think it's safer and more efficient?
Also, this is a home improvement site for "do it yourself-ers" not a "cut your overhead" site.
Watts are watts . Voltage does not change the wattage.

120v is barely enough power to run these lights. Whatever electricity that isn't used is returned to the ground. At 240 the bulb gets spark with more energy, which makes it run more efficiently. All the electricity is used because there is no ground. 240v divides the load between both the two 110v poles in your panel. Your ballasts will be cooler as well.

No commercial grow would be set up on 120v.

Your electricity will also be slightly cheaper.

Hope this helps.

I'm improving my home by myself. I don't know how much more diy this project has been. If you're hinting at something else keep it to yourself.
Keep it to myself! Your arrogance is abominable! You're clearly on a home improvement site trying to justify abusing the good nature of professionals so you can figure out how to hack your way into less overhead and more profit. This is not why the site exists.

Since that Helios 3 controller is made in the US and marketed in the US, I'll assume that the manufacturer has checked that it is legal to use. It is a smart controller after all, not just a 240 volt lighting fixture.

It is legal for some purposes. It (or actually the luminaires attached to it) are not permitted in a dwelling unit by the NEC.

You are WRONG on both points. You are just looking for someone to tell you it's OK.
Good luck with that.

no one asked for your opinion. Carry on. Hooking up a light controller has nothing to do with overhead. Its a one time project. Overhead is recurring monthly expenses. Educated professionals should know the difference.

Why am I wrong? Less amps, less heat= safer!

Also 120v is barely enough power. So how am I wrong?
Btw its perfectly legal in MI to be a caregiver and supply cannabis. This is the new gold rush. I know people making 60k-100k working very hard out of there homes. This is what our economy needs. Please stop believing in 1930's propaganda, and the failed D.A.R.E. campaigns. Cannabis is safer recreationally than alcohol and has many medical benefits to those who suffer from a variety of illnesses.

The company also sells the same unit with a 120 plug. If thats the case why do I need anyone to tell me its ok to do anything?

Hooking your HID lights up to a light controller such as this one is the safest way to run HID lighting! And putting it on its on breaker is the best way.

Your logic makes no sense. Home owners do home improvements to increase the value of their asset. So that when they go to sell there home its worth more. With your logic this person is "cutting there overhead" (not even the right terminology) because they didn't have a professional do it.


I already have a quote for 2k for a new 200 amp service and panel to be installed buy a professional. I came to this site for helpful and safe information on how to install a device in my home. Im sorry you have preconceived notions about what a plant can be used for. Adios
