"CAN"? Certainly. But you will need to run a new service cable. You'll need to have your licensed electrical contractor work out the details with your local electrical power company, and get the appropriate permits.

Can you add a 220 line to your 150 amp panel?
Yes.
Can you hook up 200 amp dervice to a 125 amp service panel?
No. If device draws 200 amps breaker will trip.
What would happen if a 200 amp breaker is used in a 100 amp sub panel?
There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
How do you find out how big your main breaker box is?
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
How many circuits can you have off a 200 amp service?
As many as you wish, as long as you do cross 200 amp limit
Do you need to change the wire size going from 100 amp service to 150 amp service?
Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
Can a 200 amp breaker be purchased that only occupies 2 slots in the panel - if so where?
No. You can not buy a 200 amp that only occupies 2 slots on the panel.
Can you add a 220 line to your 150 amp panel?
Yes.
Can you hook up 200 amp dervice to a 125 amp service panel?
No. If device draws 200 amps breaker will trip.

What is the average size for service panel for a 1200sqft house built in 1995?
It was probably a 150 amp service back in 1995. Todays services are usually 200 amps.
What is the Total power in 200 amp 3-phase panel?
100amps
Why does your 200 amp electric panel only have 20 breaker slots?
Some 200 amp breaker panels are made with only 20 slots.

Can you feed a 200 amp sub panel from a 200 amp panel?
Judging by your question I'm going to take a guess and say you should probably not attempt to do this yourself. Nor do I recommend it. That being said. You can either have your service upgraded to 200amp, and install a 100amp double pole breaker and branch it off into a 100 amp sub panel. You could most likely re-use your old panel for the 100 amp sub panel. Or... You could have your new 200 amp panel installed in a different location and your current panel wired into it for 100 amps.
How many circuits can you have off a 200 amp service?
As many as you wish, as long as you do cross 200 amp limit
How many circuits allowed in a 150 amp panel?
Panels are different. You can get 150 amp panels with 20 to 30 breaker spaces. The limit is stated by the manufacturer on a label attached to the panel. Hopefully you an find the label, sometimes it is on the inside of the cover
