"Subpanel 2 - feed from subpanel 1". Personally I wouldn't do it that way.
If you need space in the first subpanel you should just install a larger

There is nothing wrong with subpanels. I've seen brand new
residential construction that had a subpanel. The user asked if it
was legal to daisy chain them. The answer is yes. He might already
have a 200 amp main panel for all you know. He never gave us any info
I certainly would not blink an eye at daisy-chained panels that were
well thought out for the need at hand.
Maybe the 200A main panel is way at one end of a big house, and at the
other end is a 100A subpanel under the kitchen, and now he's building
out a workshop in the garage that's attached to the kitchen. But now
all the walls are finished and running multiple cables back to either
existing panel would be costly and disruptive. So put say a 60A panel
in the workshop, run one big cable back to the kitchen subpanel.
Sounds fine to me.
Sure you could contrive to trip the kitchen panel's main breaker if
you started the cabinet saw while someone was welding and the shop
space heater was runnning and the oven and the microwave and a kettle
are all cooking. I don't think that's a dealbreaker, but local code
(and the panel manufacturers) should have rules about how badly
oversubscribed any panel is, and I'd probably keep way clear of those.
Now if the kitchen panel was say 60A, and it fed the waterheater and
the dryer and the range and all the kitchen outlets, and the new
subpanel was 40A, I'd say that's a daft idea that'll be a constant
I'd love to hear more about exactly what situation the OP is in.
needing 2 sub panels will cause grief at home resale time, and looks
hacked even if it meets code........
Why should it be a matter of "needing" and not a matter of wanting. I have a
40 circuit main panel, a 20 circuit sub panel in an unfinished part of my
basement, with a 12 circuit sub panel off of that in a detached garage. They
provide me with plenty of power wherever I want it
My setup is a 200 amp 40 circuit service panel in one location, a 20 circuit
sub panel with a 100 amp main fed from the 200 amp panel, then a 12 circuit
sub panel in a detached garage,fed from the first sub panel, which has a 60
