Hi everyone, I need to upgrade my doorbell transformer from 16 V 10 VA to 16 V 16 VA, and I have just discovered my doorbell transformer is attached to the lower left side of one of my electrical panels. While I have done a number of electrical projects around the house, I have yet to work on any component that is physically connected to the electrical panel. I have attached photos of this arrangement, even though I know everyone reading this thread knows what I am talking about. I presume I will have to remove the front panel of the electrical panel to access the connections between house 120 VAC and the transformer. I suspect there is a threaded mount that holds the transformer to the box through a cut-out. Can someone please provide instructions for removal and replacement of this transformer? Thanks and advance for your assistance. I appreciate everyone's help. [attach]110561[/attach] [attach]110562[/attach]

Junction box with 3 circuits, one wire is damaged and its too short to pigtail. Do you think its easier to pull 6 #12 wires in 50' of 1/2" emt conduit by yourself? This is a homerun back to the panel. Theres a tight turn on the conduit and I am not sure I would be able to "push" the wire thru. Alternatively, I dont think I would be able to replace just the one wire without it getting hung up. vs cutting into the conduit and adding a splice box? Again this is emt and doing this I fear I dont have enough play in the conduits to squeeze it in... typically would you have to have some movement in the pipe to do this?
