First off, gotta say thanks for all the helpful advice you are giving everybody on RIU. I live in an area where marijuana is quasi-legal and every so often you hear stories about people setting up 6KW+ grows in their houses without getting their electrical stuff in line and it never ends well.
I am looking to do a smallish grow in the house, and was hoping you could advise if I should need to do any electrical upgrades to be safe...
Looking to do min 1200W, max of 2200W in the flower room with a 400W veg room.
The grow room will be set up next to the laundry room which has its own breaker box ( I think its by itself, but IDK for sure). Each fuse is rated for 30 amps. Looks like it just powers the washer/dryer, but maybe the range too...Laundry room has 240V outlet, which I would want to run everything off of if possible, except for the 400W veg light which would be on a separate outlet.
EDIT:
First PIC is schematic for main electrical box on outside of house.
Second PIC is of the box in the laundry room with 30 amp fuses
Third PIC is of the schematic for the box in the laundry room
Fourth PIC is of the main box outside the house
err i hate to ask this... but how is your budget for this op?
cuz it looks like to me your going to need to spend some serious cash on your electrical equipment to be able to pull this off...
first off- WHAT IS THAT WHITE WIRE ON YOUR MAIN PANEL DOING COMING OUT OF THE INTERIOR OF THE CAN LIKE THAT??!!! that scares the piss out of me man... and would get your house condemned if an inspector saw it. im so not kidding on that....
second- wtf is that tandem breaker doing in the main panel??? your only allowed 6 SIX breakers in the main disconnect panel.. i count 8.. thats another thing that will get you condemned!
third.. the most important thing here should be the size of the wire that is going from the main panel outside, to the sub panel in the laundry room.. i ask this because that panel in the laundry room should be taken outside and thrown in the garbage, because thats what it is! trash! it NEEDS to be replaced... its an edison base panel and its what i call a major fire trap. you need to know how big the wire feeding it is, so you can get a real loadcenter in there... the only thing you should be thinking about adding to that panel is maybe a rider on your homeowners... covering electrical fires.
im not trying to scare you, but you have some real problems that need to be addressed before you even think of adding equipment to that service... and i dont want to give you the go ahead on it cause i would have a hard time sleeping at night!
seriously... you need a pro to go over your equipment with a fine tooth comb.
what i would suggest as far as getting power to your op would be to replace the old panel in the laundry room with a modern loadcenter, however you may find that in order to have enough spaces to carry the breakers for the equipment you already have (laundry, kitchen) and the stuff your wanting to add, its going to require a 100 amp panel in there, and that is IF the wire going to the panel is #6awg or greater...
..then there is the issue of the ampacity of your electrical service coming in from the street.. is it going to be big enough to carry the additional load? from the look of your panels im not too confident, although its hard to tell without being there in person and seeing with my own eyes. you really need to have a pro there in person, because it almost looks like to me to be able to do what your wanting your going to be forced to upgrade your main electrical service on the outside of the house to a 200amp main panel, which means a new panel, a new meterbase, new conduit, new wire going to the power company's transformer.. THEN your going to have to get a new panel in the laundry room, and depending on the wire size thats already in your walls feeding the old panel, it (it being the wire, if it is too small for 100 amps) may have to be replaced as well!
in my neck of the woods that is a full 8 hours of hard work for a 4man electrical crew that knows what there doing and has all the right parts there to do it... similair jobs i have done for people like what your wanting to do, with a service upgrade and a subpanel upgrade usually cost in the neighborhood of (sit down) 1500-2500 usd depending on the amount of work needed... and thats just for the panels and wire... and that is not counting the stuff your going to need to add for the grow once you get the electrical situation worked out.
seriously i would not connect any additional equipment to that laundry room panel, it is NOT, i repeat NOT NOT NOT designed to be used with continous duty equipment like lighting for a grow op... adding a continous duty inductive load (that means ballasts in non-geek speak) to that panel will cause the main bus bars to start resonating, which will make them loosen up inside the panel, which will cause heat, and eventually, a catastrophic component failure followed by a small explosion.. and presto, house burns down! for real, you need a pro....
..and sorry for being such a downer man.
