What does the code say about situations like that, where you may have for example, a 20 AMP breaker that requires AWG-12, but an application that requires less? Does the outlet end the AWG-12 requirement? Does being inside/outside a wall change the requirements? Is it correct if the new wires are both AWG-14 (white is solid and black is stranded)? I guess that the black wire can be considered the "pump" wire, so I guess AWG-14 is ok for that one, but should I put back an AWG-12 wire for the white wire (between the boiler and the outlet)? But the new pump only requires an AWG-14. Like I said, the old wire was a AWG-12, connecting the boiler directly to the pump. That way, when the power is out, I could plug the pump into an extension cord. Instead of a direct wire between the boiler and the pump, i need to have an electrical outlet connected to the boiler, and have the pump connect into it. In the manual of the new pump (Bell&Gossett NRF-33), it says that the pump uses 125W, and requires at least an AWG-14 wire. The 20 kW boiler is connected to a 240V, 125A circuit breaker. The old pump (Bell&Gossett Series 100) was directly wired to the inside of the boiler with a AWG-12 wire. I recently changed the pump (see this for reference). My radiators would work in reverse: providing heat to the water from the ambient heat coming from the stove. I have an hydronic heating system: an electric boiler heats the water and a pump is moving it through the pipes and radiators.ĭuring winter, in the case of a power outage, I would be heating with a wood stove, but i would like to be able to plug my pump on my Honda 6500SX power generator, in order to prevent the water from freezing in the corners of the house. $130 is worth less than your life and your house, I promise. To have a professional do it, it'll probably be in the $80-$130 range, most have free estimates. Or worse, if you are confident but incompetent, REALLY don't do it, that's where the fires and electrocutions start. If you are not confident with your ability to wire, don't do it. This scenario is not as common as others, but still, it happens and it is not worth saving a few bucks. I'm a licensed electrician and see the first few steps of a electrical fire all the time. Since this splice is buried in the wall, and the smoke is most likely going straight to the attic, you probably won't smell it and your smoke detectors won't detect it until your studs are on fire, and your house is destroyed. Loose connections, under load, create heat, heat creates fire. It is dangerous because if not spliced using proper wiring methods, it can be weak, loose. If that splice fails, it'll take a sledge hammer on your wall to fix the thing. The reason you don't ever want to bury a junction in the wall is because it is a splice - splices fail. If you don't mind the look of a blank cover on your wall, do as suggested before me. Doing it this way eliminates adding unsightly junction boxes, but is definitely the harder option. The better option would be, turn off the circuit, get some 12/2 romex cable and firmly tape it to each of the existing cables and use the old cables as sort of a pull string to get the new cable to the existing locations, then junction where the original cables were junctioned. As far as I know, there is no approved method of splicing class I wiring inside of a wall, aside from that, it is both dangerous and begging for failure.Īs posted above, you can use junction boxes (he or she suggested using what is called a "nail on" or "new work" box, if the wall is no longer opened up to access the wall studs, use a "old work" or "cut in" box, this is a type of junction box that as little tabs connected to screws that when turned, flange out the tabs, mounting the box.)
