How many amps does my house need?
Asked Dec 3, 2008, 08:55 PM
I am doing a giant green make over to my house and am being told of different electrical requirements my house may need...
The sweet house I scored but have been renovating since day one:
3800 square feet, 3 bedrooms, 3 baths, TV room, dining room, office, sitting room, family room, pool, hot tub, 1 washer, 1 dryer, 1 refrigerator, 2 heating and 2 central air conditioning units, several computers, 1 server, 3 printers, a large amount of indoor lighting, speakers inside and out, light up planter boxes, gas stove, refrigerator, microwave, dishwasher, home automation system, etc etc
And have used at max 4000 kwh per month as stated on my electric bill currently.
11 kw/h dc (9.876 ac) solar photovoltaic system, 1/2 acre landscape lighting, small pond with pump, thermal pool heater on roof with new pool pump, 2 new 16 seer heating and air units, 2 tankless water heaters.
Also, sometimes we hook up dj equipment. And at times have blown breakers.
I have a 200 amp breaker at the street. And 2 100 amp panels inside the house. The solar installer says I will need to upgrade my panels inside to 2 200 amp panels. I have gotten a few electricians estimates and a couple say I need to upgrade the panels on the street on top of the 2 200 inside panel upgrades and a couple electricians say I don't.
I am way way way over budget on the greening of the house (and have many years of remodels ahead in the future) I'm contracting it out myself to save money and put more into the project and don't know which electrician to trust. Obviously it is way more expensive upgrading the street panel. I have no idea how much power at any given one time I may be using, especially after all the changes.
Any advice on the street upgrade?
