The house was built in 1900 and half of it was rewired before I bought it. I am putting in a a second kitchen so my divorced daughter can have her own space and we don't tear each others hair out. The back part where I want to put in the kitchen has the old wiring with ceramic tubes in the joists. They make pretty good whistles if you blow just right :-)
The new power supply to the house is about 10-12 feet away from the new kitchen room and it has a master shut off for the house and the wiring is covered in conduit. Is this the Panel or the sub panel?
I need to install a new box with breakers for this kitchen inside the house. How do I add up the Amps needed in order to buy the breaker? There will be an oven, separate stove top, microwave, dishwasher, garbage disposal, 2 ceiling fans w/lights with ceramic heaters, 2 indoor lights, 2 outdoor lights, fridge ( is that 110?), airvent extraction fan, thermostat for the underfloor heating and 9 x 110 power outlets for kitchen appliances a TV and plug in electric heaters (there is now forced air in the back of the house) a washer and a dryer. I think the amps are different for all of these and does it depend on the watt consumption?
Should I run all of the wiring in conduit or just the 220 wiring? Only the stove top, oven and dryer are 220 right? What guage wire should I run for the lighting, outlets, 220, is the fridge line a different guage. I should use outdoor wiring for the outside light ? What guage?
I got a quote for $2500 and that's probably very good but I can't afford it so I was planning on installing all the wiring up to the new breaker panel and then asking an electrician to hook it up to the mains. That sounds scary to me
For the plumbing I there was a old sink back there and I pulled up the floor and it's got galvanized pipe and cast iron drains going into the main drain. I think this was the original kitchen part of the house. Is there an adapter that will let me connect black plastic drain into the cast iron drain? Is there an adapter that will let me connect to the galvanized supply lines for hot and cold.? What kind of pipe should I use for these new lines? Should I run a separate drain from each of the sink and the dishwasher to the main drain or can they go in the same drain from the wall over to the main drain? Is there any kind of a valve I can put in that will help with water pressure so when I have the dishwasher on I can still use the sink? Do I need a separate ventless thing for each of the sink and the dishwasher or can they share one? Do I need any drain valves to prevent "backwash"? I was planning on adding a garden tap off the cold water supply into the kitchen is there anything special you have to do to make sure it doesn't act as a cold conductor and freeze all the pipes? The walls are wood siding like a shed so it gets cold in there. Can I take the outside tap directly off the sink line near the wall or should I use a three way supply to each of these 1. sink, 2. dishwasher, 3. outside tap from the existing supply line? Are there any questions I forgot to ask?
Lots of questions and yes I know I am certifiable. Please respond.
