The bad news is the box is getting pretty full. We calculate box fill based on cubic inches. This 4x4" deep box has 30.3 cubic inches. You are working in 12 AWG wires (do not use 14 AWG wires here!), and those take 2.25 (2-1/4) cubic inches per wire.
The number of 14 gauge wires that can be safely fit in a junction box can vary depending on the type of box and its size. A single-gang box, which is typically 18 cubic inches, can hold up to nine 14 gauge wires. This is assuming that each two wire nuts count as one wire. If a gutter splice box is used, then it can hold up to seven 14 gauge wires. 590.4(G) Splices. On construction sites, a box shall not be required for splices or junction connections where the circuit conductors are multiconductor cord or cable assemblies, provided that the equipment grounding continuity is maintained with or without the box.
Conclusion: How to Splice a Single Gang Junction Box. A Single-Gang Box, a Junction Box, a One-Device Box.. whatever you want to call it.. that’s how you splice wires in an electrical box! You start by removing the wire jacket, then striping insulation off individual conductors, then splicing wires together (that go together).
Please take a look at attached pictures of my can light junction box. Outside says max 8 14 AWG conductors. It also says 10 cubic inch is J-Box volume. . or two 14/3, but it could be argued that only one 12/2 or two 14/2 would be allowed. The Code in section 314 specifies the volume (cm³ or in³) required per wire based on size of wire, and .
Absolutely not. No splicing in a conduit body. They are only to help fish wires. Now -- there is an utterly useless exception. If the conduit body is stamped with a number of cubic inches, then you can apply the junction box fill rules instead. In any size of conduit that's reasonable for your wires, there aren't nearly enough cubic inches in the conduit bodies!
If the WHOLE circuit (not just the parts you have altered) is 12Ga you could consider going to a 20A breaker. If there is ANY 14Ga it must remain 15A, and your box fill would be easier to manage if your new wires were also 14Ga (2.0 cubic inches for each 14Ga wire "count" .vs. 2.25 cubic inches for each 12Ga wire "count") - it adds up. Of course, if you care to modify your interpretation to include the breaker boxes along the way that DO provide the current limiting, "adding breaker boxes and junction boxes to one main line of power" is exactly what your house and even neighborhood power system looks like.

Yes, it must be in a junction box. There are splice connectors available for installation in a space where a junction box is not possible, but those splice connectors are explicitly rated for such a purpose; the connector you have proposed is not. Putting a junction box in an attic is not that big of a deal. Just do that.
NEC allows the connections within the panel box and if you were moving the panel box like six feet you can splice the wires in old box to do that without any problems. Many times the new box is next to old box when you design the generator panel box, so again, not a large problem. But, do not have the Canadian code book handy. When discussing how to size junction boxes, it is best to consider some situational examples. For our first example, let's say we need to attach two 1½" conduits to the left side of our junction box, where we'll pull wires horizontally to the right side of the box with one 2½" conduit..
