I am finishing up a 203K write up and saved electric for last.
1- 100 amp fuse box with 2- 60 amp fuse boxes for 1 bedroom apartments. My scope of work will mandate it all be changed to 3- 100 amp breaker panels. Maybe even a 200 amp for the main floor unit and 2- 100 amp for the 1 bedroom apartments.
I wrote 220A coming in with 120/240 volts. The service is fed with an overhead supply.
All panels have a main shutoff.
I guess my question is would anyone else recommend a 200 amp panel for the 2 bedroom main floor and 100 amp panels for the 2 apartments. My concern is they homeowner will need new wires run to the home anyway so I propose running underground and 400 amps. Meters will go outside as part of the work.
Paul, I defer to Jim and Robert as they are the experts, but my thought (as I see many of the same properties that you do) is… As far as the supplied Amps, 100A & 60A are/have been sufficient for the size apartments you mentioned. Seeing as an upgrade to breakers should happen, and apartment dwellers tend to like their electronics (especially “Gamers”), I would prolly suggest 100/100/100 with a higher slot capacity for the mainfloor 2 bedroom, assuming that it’s panel also serves the common areas… or… add a seperate 4th panel for the common areas and size all 3 apartments with the same panels at 100A. IMO, 200A is overkill for a “standard” apartment.
Mandate for me is I have to make mandatory health and safety items. This home needs other electrical wok so a service upgrade to present code requirements would be more cost effective in the long run with a breaker panel. Neither apartments (2 apartments) has air conditioning and to install an effective energy saving install I might as well call for a 100 amp service to each unit. I will ask the electrician what makes the most sense but the fusue have to go. Unlike a regular home inspection I can call for mandatory items such as, clean the flues (chimney sweep), boiler tune up, AFCI or GFCI, smole and CO2, railings, remove torn carpet and so on.
I agree with 100, 100, 100. Thought I’d ask the guys who know more about electricity than me.
The guy buying the place is an IT professional and I will ask him what his energy needs are. For all I know he will fill the utility room with servers. Also, the upstairs apartment is over 1600 SF and is being cooled with 3 mini splits.
This is a rambler style home with a walk out in front. On the 60 amp fuse boxes, they have to go and for the same money I can get 100 amps protected by breakers. This is an insured loan so I have always asked fuses be replaced with breakers.
Fair enough. From an electrician’s or electrical inspector’s perspective simply eyeballing the service size wouldn’t be good enough. A load calculation performed according to Article 220 of the NEC would be needed but I do see where you’re coming from and if it’s acceptable to the parties that you’re dealing with then all is good.
I much appreciated the responses, as well as the suggestion of a load calculation which I have done but not for the 203K rehab loans. I think I will consider load calcs from now on though. It would make for a better report on some projects.
