You have a copper to aluminum splice on what is probably the circuit for the electric range.
Of course it might be tin plated copper not aluminum.

Is that the bx cable wrap tied to a ground wire?

It is easier to change direction than it is to forget where one has been.

Well what Bob said, but then it may be protected against corrosion…can’t really determine this unless you open the splice.
Next...someone took a lot of time to wrap the neutral on the se cable but they wrapped it with the wrong color tape....in fact why wrap it at all 
Only other thing I see is that it is a CH panel....ressie grade....never did care for these

Dennis,
Maybe that is feeder, not service entrance. Don't see a main in that panel, however, guess it could be a back fed breaker in the top on the left (out of sight in the photo).
If feeder, the neutral would need to be insulated (and, no, taping does not cut it).

If ya look real close to the left it looks like there is a breaker there…most possibly a 2 pole…probably even a main 2 pole breaker.
Witrh a solid copper wire coming into the top of the thing and attached to the neutral buss....it is quite possibly a main panel....better yet look at the neutral buss.....see the bonding jumper there? Yep, everything says it's a main panel....even if it does not have a main breaker...the se cable is more than likely coming from the meter socket......and if one is going to insulate the neutral wire....why not do it right?? No real reason to insulate the thing anyway.

I agree, I should have shown the picture with the wires attached to the breakers. Definitely aluminum and yes that was aluminum attached to copper wire.
This was a 240 volt circuit, stranded aluminum wire running to a 40 amp breaker. The tape color would open a whole new can of worms since it was a three wire installation. Which would the third wire be in this case, neutral, grounding or both?

A 3-wire 240V circuit would be H-H-G [except for existing range/dryer circuits which could be H-H-N]. A 4-wire 120/240V circuit would be H-H-N-G.

Robert that is not true of existing range and dryer circuits.
They are 240 volt 3 wire circuits.

| 250.140 Frames of Ranges and Clothes Dryers.
This section shall apply to existing branch-circuit installations only. New branch-circuit installations shall comply with 250.134 and 250.138. Frames of electric ranges, wall-mounted ovens, counter-mounted cooking units, clothes dryers, and outlet or junction boxes that are part of the circuit for these appliances shall be grounded in the manner specified by 250.134 or 250.138; or, except for mobile homes and recreational vehicles, shall be permitted to be grounded to the grounded circuit conductor if all the following conditions are met. (1) The supply circuit is 120/240-volt, single-phase, 3-wire; or 208Y/120-volt derived from a 3-phase, 4-wire, wye-connected system. (2) The grounded conductor is not smaller than 10 AWG copper or 8 AWG aluminum. (3) The grounded conductor is insulated, or the grounded conductor is uninsulated and part of a Type SE service-entrance cable and the branch circuit originates at the service equipment. (4) Grounding contacts of receptacles furnished as part of the equipment are bonded to the equipment. |

Good call. The wire nut is green. Also the wiring size changes.

"Yep, everything says it's a main panel....even if it does not have a main breaker...".
If more than 10% of the panel is 'lighting' you need a 'main'. I'll bet it has more than 10% lighting circuits.

Joe T,
Please explain how your reference is something we would see or look for in the practice of a home inspection. Please elaborate on the grandfathered provision versus what is technically required as per the NEC for new construction, and explain how you would have written this up.

It should not concern you (HI's).
IMHO this is outside a visual inspection. And if you removed the dryer plug would you 'pull' the range to check it's connection?
I would only be concerned if there was a range rcpt. for a dryer.
