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
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
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.
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
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.
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....
