The voltage across the main entry from the hydo to your house is 220v, not 110v. Your calculation is not right. If your main entry is 100A and

本文发表在 rolia.net 枫下论坛If your main entry is 100A , it is no problem to add a 40A load to the panel for your basement stove in terms of power capability. The only problem for you is the panel--not enough space.

So, you have to change the panel. The following is an example to how to do it in a professional way:

1, Call a contractor ask for a free(?) estimate
2, SIgn a contract (He/She will do the rest, so I don't have to talk about that)
3, Check all the appliances and ligh tings
4, Pay him/her (about $1000)

The following is an exmple how to do it in DIY way (it is a practrical way)

1, Call a lisenced electrician to check your panel and main entry cable, He/She should make sure that your main entry cable is for 100A
2, Call your local hydro to disconnect the power (normally free of charge) and set a time for reconnection
3, Go to Home Depot or other supplier to buy a panel set (panel and circuit breakers) and other accessories. That will cost you about $230
4, Change the panel and some of the circuit breakers
5,Check all the appliances and ligh tings
6, Pay the electrician (about $350)

I have assumed that your main entry is 100A.更多精彩文章及讨论,请光临枫下论坛 rolia.net

  • 枫下家园 / 住房话题 / 请教懂电的朋友:想在Basement装一个电stove(220V),但electrical panel已经满了。我一定要upgrade panel box嘛?谢谢。
    • 是的,而且,好像还不便宜。
    • 算算容量吧(电器的瓦数),如果总功率有余的话,应该可以自己搞。不过如果出了事好象保险公司不赔。
      • 谢谢指点!算容量把瓦数加起来之后同什么比较呢?我只知道我的panel是100AMP。
        • 对不起,没有注意这个回帖。如果是100安培,那么总功率是100A×110V=11000w=11kw。注意象冰箱的启动电流要比正常工作电流大。好象坛子上有刚拿到电工证的,帮帮忙啊!
