comment Why do I detect voltage on my ground of surge protector?
I'm fairly sure surge protectors work by dump surges to the grounding conductor, so I'd say it's working as designed. If you're seeing excess voltage on the ground of the surge protector, you should have the electrical system checked for excessive spikes.

comment Any problem with installing two identical circuit breakers in series?
One problem I see is that if the circuit ever loses power, you'll have to check in two places to figure out which breaker tripped.

comment Any problem with installing two identical circuit breakers in series?
@TheEvilGreebo Most modern circuit breakers offer both overcurrent and short-circuit protection (as well as ground- and arc-fault protection). You'll see two ratings on the breaker, the normal current rating on the handle that everybody pays attention to. This is the overcurrent protection rating, and it is usually a time-delayed mechanism. The other rating is the short-circuit rating, and is typically 10kA or so. During a short-circuit, current in the circuit will raise very fast. A time delay could be dangerous, so the short-circuit protection is usually "instantaneous".

comment Terrarium electric board
You should be able to estimate the load (which is the way overcurrent protection is usually selected), using the labeling on the devices you'll be connecting. Current (I) = wattage (power)(p) / voltage (V), though some devices might have current ratings listed directly. This will give you the current for each device. Since it looks to be a parallel circuit, total current (It) = I1 + I2 + I3...

For rounding over the edges, a router is the way to go.

comment How safe is having my boiler in my daughter's bedroom?
@drake035 Avoiding the unavoidable is not possible, you're correct about that. But why would you tempt fate, if you didn't have to? You're comparing things that are far beyond your control, with something that is easily controlled. A 0.0001% chance of something happening, is still a better chance than 0%.

comment dual GFCI circuits with multiple protected outlets, all sharing a neutral
If your circuit is actually wired like this, it's a mess! First off, your GFCI receptacles are hooked up backwards. In your image the grounded (neutral) terminal is on the left, but you have the ungrounded (hot) conductor connected to it. Secondly, because of the shared neutral you'll always have unbalanced loads through both GFCI receptacles. This is going to cause one or both of them to trip, as soon as any load is put on the circuit.
