circuit breaker boxes

Page 3 of 3  


Figure one breaker for each fuse , and two each if you have doubled up on circuits to fuses.
Get the cost from your utility for the monthly charges of 125 and 200 amp supplies. Get the cost to upgrade from your current service to 125 or 200 amp.
If its the same go for 200 amp.
If you are planning on selling the home go for 200 amp supply.
Plan out your breaker panel, seperate kitchen from the rest of the house , allow for water heater , stove , air conditioning on seperate breakers.

What do you mean by this? You pay for usage.

That's silly. You pay for the electricity you use, not for the capacity of your service.

It won't be. 200A panels are more expensive than 125A panels, and 200A service requires heavier (and therefore more expensive) service entrance conductors. The *labor* should be pretty near the same, but the *materials* will definitely be more expensive for 200A.

Missed the part about the home being only twelve hundred square feet, didja? 200A service is a nice feature to have, but having "only" 125A service on a home that size shouldn't have much, if any, impact on resale value. At most, I'd expect the homeowner to recover the extra cost at resale, not realize any profit from it.

No, let the *electrician* do that.

been getting by with a 60 ampere service you probably do not need more than a 100 or 125 ampere upgrade. Per Code Section 220.83(A) for upgrading an existing service for additional loads where air conditioning and electric heat are not added the following is used: First 8 KVA of load at 100 per cent Remainder of load at 40 per cent Where load is 3 VA/ sq.ft or for you 3 x 1240 = 3720 VA Small appliance load = 3000 VA Household range (usually 8000 VA) All other appliances pemanently connected (like a boiler motor or bathroom fan) or fastened in place (dishwasher) at nameplate ratings. (For good measure just add 3000 VA here.)
This gives 3720+3000+8000+3000 = 17720 First 8000 VA at 100 per cent + 0.40 x (17720-8000) = 11888 VA 11888 VA / 240 volts = 99 amperes So using this calculation a 100 ampere service would suffice.
If you are adding or have air conditioning and electric heat or are planning to add a two car garage and a shop, etc upgrade to a 200 ampere service.

11888/240 = 49.5 amperes in place of 99 amperes. Also, I should have added 5000 VA for the hot water heater. 17720+5000 22720 VA 8000 + 0.4(2272-8000) = 13888 13888/240 = 57.9 amperes

This is a beautiful illustration. keep in mind that these figures include an electric range and dryer that may not exist.

You can ask for a service calc. This will take in square footage, and electric usage from major appliances.
Now the knee jerk reaction is to get the 'biggest' but the trend is toward more energy efficient applicances, and with a limited square footage, it might be most cost effective to get what you need.
Just thinking out loud....
