I’m replacing the existing light switch with a built-in timer, but I have a problem: I cannot use twist-on wire connectors as they occupy too much space in a switch box.Is it safe to use just an electrical tape?
The NEC does not allow you to use butt connectors on wire unless it is stranded. Electrical tape is not an approved mechanical splice. Soldering is not approved for that use unless the house is wired with Knob and tube, if that is the case you need to use the correct knot and then solder it. you won't have room for that. So that leaves the quick splice connectors which probably will take up the same amount of room as a wire nut. If all else fails you may have to install another cut in box above the existing switch box and patch the hole left by the old box.
Buy using a pair of dikes and a butt connector, things should work out. Have fun.
obviously tape by itself is the worst idea. A butt splice would work just fine
DO NOT USE A BUTT SPLICE! Butt splices can come loose and cause a short in the system, or even a fire. The best thing you could do is solder the connection and then use a quality electrical tape.
this is against the national electric Code to splice wires in this manner. the only genuine problems I see right this is: a million) Butt-splices are no longer made for everlasting abode wiring. they do no longer seem to be an authorized technique for splices. 2) your place catches hearth. The plastic around the butt-splices will soften, however the metallic will nonetheless be seen related to the twine. as quickly as the hearth inspector nicely-knownshows this, it won't count number in the event that they have been the reason for the hearth or no longer, it is going to bypass onto the checklist this is sent on your insurance organisation. And all of us know the place this might bypass. The insurance organisation will look for any reason to reject a declare. (and working wires on superb suited of rafters has been a typical prepare for a protracted time, with the aid of fact the code adjustments each 3 years, so what could be criminal interior the 2005 code wasn't criminal interior the 2008 code.) 3) Any splice SHALL be in an UL listed enclosed field. I applaud you for asking the question. i'm hoping you may stay with your restoration. stable success and could God bless.
