What are these electrical connections ?!? I know somebody knows!
The 2 black tape'd up square objects that connect the supply lines with these smaller lines.. what are they? (the boxes)I know these are my strip leads, I just wasn't sure if these were some type of fused link for regulating the amperage from whats supplied. notice the step down in gauge.
Thanks for the clarity!

Probably just splices but you could disconnect the power, unwrap the tape and actually see what they are.

Square splices? Never seen that before. If I was on site I would already know but Im not, so I was hoping for a quick answer from someone who knows. Maybe they will be by here in a minute. The breaker is 100amp so I'm thinking they didn’t just “splice” it. Ive just never seen anything inline you could step safely down with.

Wow. You learn something new every day, it could be that last one. I just cant believe its on a 100amp breaker, isnt that dangerous?
i was really hoping it was some type of fused connection id never seen.
Guess im just going to have to go check it out personally.
thanks again!

Those are bugs. They need to be split bugs if there is aluminum and copper wiring involved.
Copper and aluminum wiring cannot touch.
Technically..... electric furnace manufacturers require copper supply wiring only so that
needs to be looked into carefully as your supply cable is aluminum.
As mentioned... it definitely looks smaller than 100A wire.

Im only going on what the hvac technician says. He wants to swap out those splices and install a 30amp disconnect to protect the equipment from the excessive amperage the breaker would allow in a short. He is the one who told me it was a 100amp breaker And the equipment is in jeopardy until something is done about it. Even though like i said its a factory install as shabby as it is and hasnt had a problem in the 30 years its been built.
if that is in fact just a splice, i tend to agree with him.

At the equipment end.... in the picture needs to be a service disconnect.
It could be a 30A disconnect to protect the equipment but that does not protect that cable from there to the panel.
You should look on the gray service cable and tell us what it says on it.
The breaker in the main panel must be sized to protect that supply cable.
If that is an electric furnace.... 30A is kind of small.
30A would indicate approx 6000 watts of electric heat.
