2 200 amp panels

[MC9]

I have a warehouse that has a 3 phase 200 amp service feeding a 200 amp panel. I need 2 200 amp panels right next to each other. Everything is within 20 feet of each other. Suggestions on easiest way to get this done?

You can't just add a 200 amp panel unless the calculated load is 200 amps or less. Are you upgrading to 400 amps? Do you need more space? Did you calculated the needed load?

Th calculated load is less than 200 amps. I am not upgrading to a 400 amp panel. what I need is to feed 4 100 amp subpanels to various stations in the warehouse. Could I just run the 4 100 amp subpanels off the original 200 amp panel? With only the 4 100 amp panels being used in the 200 amp panel.

I did under 200 amps. Im not upgrading.(or should I) What I need is to have 4 100 amp breakers feed subpanels supplying different stations throughout the warehouse. These 4 subpanels will be the only things being used by the 200 amp panel.

I think you are trying to be too brief. If I understand correctly, 200 amp 3 phase is the service, and it is sufficient to feed all loads as calculated per the requirements of the NEC. AND you are comfortable with the amount of additional amperage available for any future anticipated loads. If yes, then:

Why do you feel you need two "200" amp panels? Quotations because, what makes them 200 amp panels? Is that two 200 amp panels each fed from a 200 amp breaker at the service? Is it one 200 amp feeder with a 2 section panel?

Why do you need another one? As long as the loads are sufficient, you can just install two additional 100 amp breakers in the panel if there is room. Perhaps a sketch would describe what you are doing better.

Are you licensed???

This is what I have:

200 amp service-------->200 amp disconnect-------->200 amp panel

This is what I want to do:

200 amp service--------->200 amp disconnect-------->200 amp panel-------->4-100 amp sub

OR

200 amp service-------->200 amp disconnect---------->200 amp panel 2-100 amp subs-------->200 amp panel 2-amp 100 subs


Each 100 sub will have 1-60 amp & 2-40 amp breakers running constantly

Hopefully this clears it up a little.

I have been out of the field for 5 years. Scheduled to get re-certified in a April. Studying and looking for work.

If you are intending to put the two 200A panels close together, you are probably better off putting in a home run to each 100A panel if you can put four breakers into the main disconnect.
If not, just use one 200A panel to feed all four subpanels.

Sir Alwon, please direct me to the appropriate code section for your response. Thank you.

What I was getting at was that you cannot add more load without calculating the load to make sure you are not over 200 amps. Sure you can add as many 200 amp panels as you wish but generally your load is increasing. Some people believe if they add a 200 amp panel then they have another 200 amps...

Indeed, thanks for the clarification. Yes, one must consider the service limitations. I had a "gig" (sorta) once for having more than ten, 20 amp breakers in a 200 amp panel.
