is this to code?

Nope - that should be pigtailed properly... you cant have 2 conductors in a single terminal. It also looks like the wire is a single conductor/solid?! Perhaps someone installed a wifi amp meter or something so that they can monitor the house electrical usage from their phone and compare it to the electricity company's invoices.
Either way, it's not installed to code.

It isn't just having a double tap. That wire has no overcurrent protection at all.

I've done some dumb ****, but tapping into an unfused line ain't one of them
Whose got the pic of the drywall screw tap into the main feed?

That should be in a dedicated breaker as close to the feeder as possible
The mfg isn't going to recommend double tapping the line side of a panel.
No offense but your questions are irrelevant.

This info should have been in the first post.
Instead it’s click bait thread.
i didnt know you needed to know all that to tell me that two wires cant be connected like that.
Not a fan of connecting type 1 SPDs straight to the line side, I like to have as much overcurrent protection as possible everywhere. You are correct in assuming that this is permitted by NEC under 230.82(4). Putting in a breaker to me is cheap insurance and doesn't require messing with the main lugs when you inevitably need to replace the SPD. Also if this is one of the units that makes an annoying alarm noise when it is due for replacement you can't just flip a breaker to silence it until replacement time.
You will not find a residential load center that have lugs rated for two conductors IMO. So yes, it's prohibited.

Numerous (but not all) circuit breakers, switches, and receptacles accept 2 wires of the same size under a terminal. In this case NO.

So you posted the same picture on a diy forum and were plainly advised it’s not to code. Were you hoping to get a different answer here?

They need to be consistent. The instructions ****!
If you can't figure out those instructions, you have no business in a breaker panel
Yikes, having a rough day??
I didn't suspect the manufacturer would recommend that, nor anyone else, however whatever they do recommend is relevant.
See Page 3, step 6. "Hook it to a circuit breaker."
"Connect the white (neutral) wire to the
neutral bar. When no neutral is present,
connect the white wire to ground.
Connect the black wire(s) to the circuit
breaker."
Since this is 240 you will want a 2 pole circuit breaker for the two black wires, move the white to an open space on the neutral bus. Or have an electrician do it, if this was installed by an electrician, call a different one. I do not see a breaker size stated, I'd go by the gauge of wire on the leads, is it 14? If so 15 amp breaker.
Also, See Page 4
"Electrical equipment should be installed,
operated, serviced, and maintained only by
qualified personnel. No responsibility is assumed
by Schneider Electric for any consequences
arising out of the use of this material."
Be careful!

The breaker would have to be identified to handle 2 wires... and most of the breakers/switches/outlets that I've worked with and seen do not have this listing. Maybe they're more common in the US though *shrugs*
Either way,.. his main 100A breaker certainly doesn't appear to be rated for it.
That's for sure.
But for the manufacturer, I would except your documentation to be correct. The wiring diagram does not show a cb in use.
An hows about a cb rating to attach dem wires to.

You only shared a excerpt of the instructions, so I don't know.
Unfortunately, ****** instructions are becoming the norm

ooofff definitely not installed correctly.... there are very specific directions to install those and doing what is show in the pic is definitely not one of them

huh? he asked how the manufacturer says they are to be connected. how is that irrelevant?

oh boy. can someone pass the popcorn please

no it wasnt. the wires are connected to the line side of the main breaker not the load side... the load side of the main breaker is bolted to the bus bars below the breaker.
Missed my sarcasm?
Instructions said to put black wires to breaker. That was done right?
Obviously that wasn't what was intended by that line in the instructions.

Those homeline breakers are the only ones I'm aware of that can be double tapped legally.
Would have saved a lot of problems.
Just curious if this is a subpanel the wires feeding the main breaker don't seem to be thick enough to be service wire and appear to be lighter gauge than the heavy red and black attached the 40 A breaker. Unless the red and black are the service wires and they're backfeeding the main bus? Doubt it but from the looks of it it wouldn't surprise me...
The main has copper, I bet that 40A has aluminum
