Upgrading Power Service In New Home Build


Getting ready to move on a new build which has 200 amp service vice 400 amp service that we currently have. The current house has 4 dedicated 20 amp circuits in the media room. I asked the builder to add the same amount in the new house,,but we have to wait to get approval from the electrical section, and home builder. So, thinking that a negative decision will come back, do I just need to contact the power company for a service increase, say 100 amps or so, and deal with the power company directly after the build so that I can get the service, then ask an electrician to add the dedicated circuits and wiring to new outlets in the media room? Seems like a lot of work if the builder can't accommodate me. 

Anyone have experience adding service upgrades to their new or older homes, and how did you add the extra circuits to your listening or media room? FYI, northern Virginia, dominion power will be the power service provider. Thanks in advance.

I am building a new home in Arizona.  Unfortunately, the original developer only provided service for a 200 amp sub-division.  I needed a 400 amp system which was part of my original architectural guidelines.  Once that was established, I went to the electrical company and they did an engineering study to determine how this was going to be accomplished.  Consequently, it is going to cost me an additional $7,000 to trench for this service.  I will have a separate 20 amp system for my theater room an a separate 20 amp system for my 2 channel room.  I am not a happy camper but you have to do what you have to do.  That could have been money I could have used to buy an upgraded $K sony projector. 

There are some good reasons for not upgrading. :)

The resistance in the wires actually improves surge protection, and reduces interaction from other buildings and other services drawing power.

Your mileage may vary, but upgrading an electric service in amperage is not all positive.

Now, having your own transformer.... that's helpful. :)

Best,

Oh how I love country living. I just realized I have my own transformer!!

(But I have a nagging fear that there's loads of crap on that line anyway.)

erik,

Of all the potential sources for power line crap, I never thought of elevator motors. Thanks for reminding me that I should be grateful. Maybe my neighbors electric fence or welding shop could be a country equivalent.

What's a good way/tool/process to check AC power contamination? I've seen simple plug-in device detectors mentioned in articles/posts but I can't seen to find one to buy.
