Transformer installation
My house has a 16V 10VA transformer for the doorbell. I bought a 16V 30VA transformer, and tried to install it. Easy? Simple? The 10VA transformer is attached through a knockout on the side of the breaker box. The 16V wires are attached to the outside, while the high voltage wires are threaded through the knockout hole. However: * The three high voltage wires are connected directly, without any wiring nuts, to the breaker and the ground bar. * The green wire and one of the black wires are attached to the ground bar, and I **can't** loosen the screws that hold them to the ground bar. If I can't loosen the ground bar screws, I will have to cut and strip the existing wires, and use a wiring nut to connect the new transformer wires to the existing wires. * The other black wire is attached to a 15A breaker. Questions: 1. Why is the existing 10VA transformer double grounded (ground and one side connected to the ground bar)? 2. Is it OK to attach a 30VA transformer to a 15A breaker? The circuit only powers the chime solenoid and the video doorbell. They say 10VA is not enough for both, but will they pop a 15A breaker? 3. I only have small wiring nuts. Will I need to buy larger wiring nuts for the larger gauge wires?

I have the same situation. Ground and one side connected to the ground bar? That's normal the neutral (normally white wires) and the ground (normally bare or green) have different functions but both attach to the ground bar. Is it OK to attach a 30VA transformer to a 15A breaker? Yes. Not a problem at all. Will I need to buy larger wiring nuts for the larger gauge wires? Without seeing them it's hard to say. Likely if any wire nuts came with the new transformer they'll work but no guarantees.
