wiring under existing floor

In upgrading wiring in a 100 year old house, we came across a spot on the third floor where they had run wires up a second floor wall and then connected that wire with marrettes to other wiring which goes under a few more floorboards to a light switch and on up to a ceiling fixture. Would it pass Canadian code to put a junction box under the floorboard to join the wires? If not can we run wires along the same basic path as long as there are no connectors? The issue is that the rooms on the third floor do not line up with the rooms below and there is no easy way to run wiring up the walls to intersect with walls on the third floor and there is no attic above the third floor to run wiring.

Yikes ... sounds a bit scarey.

A junction box has to be accessable and have an appropriate cover fixed to the junction box. Unless you are going to leave an access in the floor it might be better to relocate it.

The thing is while junction boxes are allowed for splicing together wires there is always a potential problem at a splice.

If you can have the cable from the switch run directly from wherever the feed point is and make the splice there.

The cable can run under the floor as long as you fasten it to say along the center of a floor joist .

In the event its needed, a listed, floor-rated junction box should be acceptable, albeit bulky, expensive, and a conspicuous plate.

Yep ... also called marr connectors or wire nuts.
I think "marrette" is a french thing meaning connector?

Nope ... not snowing yet .... at least around here .... nice balmy 74 today.:D

Yup I'm sure the CEC is no different from the NEC in that all splices need to be in an approved junction box of some type and accessible without removing building structure.

Yep ... for those reasons and getting rid of a junction .... better to redo the cable in my opinion.

Re: wiring under existing floor

Things are similar .... common sense as well.
J-boxes need to be accessable and not hidden.
