Here is my situation. I have an old cabin that is wired with the old 2 wire with no ground. The existing main is a 110v 60 amp box with 2 screw in 30 amp fuses making 2 circuits that are fairly equal in load distribution.
It is just a small 1 bedroom, small kitchen, 1 bath, living room cabin. I do not need much to power it and any chance of needing a bunch more later is nil. The existing wire itself is in good condition, but the main box has seen better days and will be replaced with a new metered 220v 100 amp main with 16 breaker slots...more than adequate for any expansion I will ever need.
I want to, eventually, have rewired everything to 12/2 with a ground (in case any outlet at some point needs to be upped to 20 amp), relocate some (most) outlets (replacing all of them with grounded outlets), adding a few new circuits, etc...
Due to finances and time to spend on it I need to do this in stages...so these are my questions. I need power to everything existing as I do this.
1. I intend to start by installing the new metered main first...new #2 wire from the weather head to it, new grounding rod, permitted and to local code, etc. Can I connect the existing 2 30 amp circuits to the new main?
If I can, how do I make that connection (I am assuming, but smart enough to ask first) each hot to a separate 30 amp breaker, each neutral to the neutral bar and the neutral bar in the new box connected to the ground bar?
2. As I add the new circuits and wire them to the new main (and get the chance to add, move, divide the load distribution) I assume I wire them the normal way...is there a problem with "mixed" 2 wire non grounded circuits and the new 12/2 with ground circuits being wired together in the main? (on separate appropriate amp breakers of course)
As I have reached each stage in this I will be disconnecting and removing the old circuits, wire, 2 prong outlets and breakers completely...just not all at once... which is why I ask if it is okay to have them "mixed" for some of that time.
I appreciate your response/advice...
