Help Understanding Estimate


Get another quote. Three minimum, IMO. I also wonder why you need a 400 amp service. I have a 200 amp service and the whole house is electric @2500 square feet. I have a 40 space panel with tons of room left for expansion.

I also agree the meter and the service entrance cable be pulled out and replaced.

Ask about a meter main combo. A meter socket and load center in one enclosure. Then your main service panel becomes a sub panel. This will give you a disconnect outside and a few extra breaker slots outside. See if the POCO will bury the new lateral, transformer to meter. It looks like a straight shot if you leave the meter where it is.

I don't know where you live, but that first quote seems awful high.

You mentioned "000"? For the lateral, 3/0 copper is correct for 200 amp, not 400. But they will do what they want.

It is old, and probably isn't rated for 200 or 320/400 amp

I guess I should get some more estimates and try to understand what exactly I need to do. This is my first home and my first "estimate" so I'm learning as I go. You guys' are very helpful and I very much appreciate all the information you provide.

Thank you.

So it sounds like what I should be getting estimates on is replacing the panel with a 200 amp panel (should I be concerned about what type? What is "Square D"?). Replace the service meter (why?).

Square D is a company that makes overcurrent protection devices (circuit breakers) and many other electrical transmission equipment.
I would go with Square d, General Electric, or Siemens.

There is clearance around the panel, however, if I wanted to re-frame the wall it's mounted on or replace the wood panel with drywall, would that need to be done before the new panel is installed or could it be done later?

Re framing might need to be done before.
Not sure about the re framing, maybe some pictures could help?

Its an opinion and I respect it but 220/221 can you elaborate why 4K dollars more from the first electrician is valid
Different scope of work.


I also still can't understand why, in 2008, the NEC allows unfused, unprotected service conductors. :j ester:

Someone needs to manufacture a "ArcFault" meter socket that costs $1,200 and every house will be require to have one!

OK I misunderstood the scope of the work.
The first guy want to replace the whole service.
The second guy only wants to replace the panel.
If the existing panel is 200 amp then it can be done. But you can't replace a 100 amp panel with a 200 amp without replaceing the whole service.

Replace the whole service. Get more estimates.

My first thought was "sure you can" because the panel is rated for max 200 amps.

Then I realized that things are done differently back East. There is no protection at all on that service cable on either end.

My second thought is, what difference does it make. If you are allowed to install a service panel on 100 amp wire with no 100 amp main, is it somehow safer than a 200 amp main breaker installation?

If the service cable had proper protection outside, just after the meter, you could install an 800 amp panel with no issues because the feeders are proteted.

Please, someone tell me that you at least have to povide a main breaker panel in these types of installations now.

Yes you need a main breaker, in the main panel, on this type of installation.

So, in conclusion, the 200 amp main breaker panel proposed by electrician #2 will not work unless he can change the main to a proper 100 or whatever the existing cable will support.

The panel is not the issue, the breaker is.
