View Full Version : 2 Wire (no ground) - split into 3 wire?

I have an outside "sun room" that I am renovating. The only power into the room is a 2 wire outlet that runs directly to the box. My electrical knowledge is limited to basic circuit stuff.

My renovation includes a ceiling fan, 4 sconces, 2 outlets, an and outside light.

First question, after I get the wire from the current outlet to the switch box can I run a "hot" wire (red) to the fan, so that the fan will always have juice, even if the switch is off. Is that "safe"?

Second Question, I plan on putting 3 switches in 1 box. 1 for the fan light, 1 for the sconces, and 1 for the outside light. Can I jump all 3 (4 if you include the hot line for the fan) off the single hot going into the box? Would it be as simple as tieing them all under the same wire nut?

Third question is their anyway to ground this stuff? As I originally said the old 2 wire coming in is original to the house so no ground. The moisture/humidity that gets into the room is slightly concerning and I just want to make sure I don't surge the house flipping on my switch one day. Would a GFI in the original outlet box help at all?

Thank you all for your time and for any answers.

A GFi offers ground fault protection, but DOES NOT create an equipment ground.

Since you going through the renovation of the sunporch, why not install a new cable with ground to this area?

No room in the fuse box for any more jumpers

Not sure what you mean by "jumpers". I am simply suggesting you change the two wire cable to a three wire that includes a ground conductor. The new cable can use the same circuit breaker or fuse as the existing cable.

Didn't even think of that.

I may do that.

Is the rest of my wiring plan acceptable?

That's why we get the big bucks.

I do not see any problem with your wiring plan, other than why not have a wall switch for the fan?
