Remodeling kitchen - to what extent do I need to bring up to code?
I'm in the process of remodeling my kitchen and the electrical aspects of it have so far been some of the most mysterious, especially in terms of code requirements. This being a "retrofit" and not new construction only complicates things. Obviously, I want to meet code where practical, but want to save time and money where safety and functionality will not be compromised.
I've gleaned that I need to do things like add GFCIs, install outlets at the required spacing/locations, etc., but then there are lots of details that have yet eluded me, namely:
Do the disposal, dishwasher, and microwave all require their own circuits? I currently only have a dedicated circuit for the disposal, but am planning to add the other two. It would be practical in my case to put the disposal and dishwasher on the same circuit, if that would be allowed.
Do outlets need to be both GCFI and tamper proof?
Do all outlets need to be grounded, including floor-level outlets? Can I connect a ground from another circuit to amend an ungrounded circuit?
Can I use an extension cord to connect my 220v range to the existing outlet? Do such cords exist? Or will I be forced to move the outlet?
NEC 2008 GFCI must be Tamper proof, all outlets from what I have read
Microwave if built in needs a dedicated circuit
Countertop if a high wattage model its a good idea
2 20a GFCI protected countertop circuit MIN required, you can have more
Fridge can be on one of these, but I run a dedicated 15a for mine
Dishwasher may need dedicated, usually they take up a load of power
All circuits need to be grounded, do not borrow one from another circuit
Do not use a 240v extension cord !!
I asked my city building department for a consultation visit when I did a complete redo on my kitchen. They had me add a couple things, changed another, left most as it was. Saved me effort, time, money - and ensured all passed inspection without any issue or redo.
