Hi,a nd welcome to JA
how many circuits are in your main panel?
Well, I'm not sure how to answer that. Naturally, I could just count the breakers, but do I count the 220 V double breakers as one or two? Also, do I count the 100 amp double breaker that is for the sub panel?
count all the breakers, count the double poles as 2 including the 1 feedin the 100 amp panel
should be 30
Ok, this is what I counted: 15 - 20amp on one side and the other side is filled with 5 extra wide breakers.
Oh, I forgot to include the extra wide one for the sub panel.
I can tell you this. I would not add anything to this service without getting an upgrade tot he incoming power
you can not just change the 150 amp breaker to a 200
OK. What does that involve?
because the wiring from the meter to your panel is probably not rated for that
Here is what you do
find an electrician who gives free estimates.. Have him come out and acess the situation. Tell him what you are looking to add
I would say it is pretty likely that your service is maxed out as it is
I am sure that in a garage workshop, you would be adding some circuits that would draw quite a bit of power
Could you please elaborate on what I need to know from the electrician?
just have them look at your existing service, and tell them the type of equipment you wish to add in the garage
upgrading you to a 200 amp service would not be that hard or expensive, but it is something a licensed electrician would need to do
If I did have it done, would they still use the same box, just updating the wires from the meter to the panel?
yes, and the main breaker
and the wires from the meter up to the service drop from the utility company
That sounds crazy expensive. All residential electrical in my area is underground.
Am I right on that?
well the power company should upgrade the wiring into the meter at no charge
I really cant tell you what it would cost in your area
Just get a free estimate
Thanks anyway. I'm sure I'll have more questions again later...
