should we upgrade
We recently bought an older home that has been remodeled and rewired. They only have a 100A main. Wondering if this is enough or should we upgrade to a 150 or 200. There are 4 ceiling fans. 2 window air conditioners, kitchen appliances and washer dryer. We have a family of five with tv’s and dvd players and all the other things that need charging and stuff. Not too keen on how much we will need. Any suggestions?
The appliances you listed are more or less irrelevant in the amount of power they use.
The biggest power requirements that could necessitate a service upgrade come from the following if they are electric: central air conditioning, baseboard heat or central heat pump, water heater, stove/range/oven, spa, welder, or heavy shop tools.
If you have gas or oil heat and no central A/C, then 100A is probably sufficient for most homes. If you have a lot of the listed items or plan to add them in the reasonable near term, then you should perform a “demand load calculation” to determine just how big the service should be.
