Default Can anyone explain to me the thing squared in red

I am new owner and Since Sandy beat my house up. I have few damage and still learning. There is thing snap from my house. It is part of electric power line from outside. It might be neutral line (no power just ground)?

Appreciate anyone teach me anything


Second question is the electric break panel. There are two big thick powerline coming in the the main breakers. should those both have electricity?

The cable strain relief has pulled out from your wall due to horizontal wind force deflecting your Service Entrance cable.
Apparently the strain relief bolt stripped and the nut and washer fell down inside your attic.

If this is not fixed your SE cable will have a short life. Copper cannot stand much tension
so the steel messenger cable that fastens to this anchor
carries the bulk of the tensile force.

If your AHJ permits it, get a heftier strain relief from an electrical supply house and have it fastened properly on a non-rainy day by someone who knows what they are doing
or
who is not afraid of insulated wires carrying 240V while working on a ladder.

If the strain relief bolt is not stripped
you can get a 1" long stainless steel or galvanized bolt connector that has female threads inside
and use this to couple the strain relief bolt to another bolt fed from the inside of your house.
That way you don't have to mess with the messenger cable.

There should be some sag in the cable when you're done. Look at other undamaged houses to see how much sag in how much distance the electricians have put in these cables.

I've re-anchored the strain relief bracket on my 50 YO house with two lag screws; it was starting to pull off and fortunately I noticed it while pulling ivy off the walls.

yes, the two large black wires coming into the main breaker inside the panel should each have 120VAC to ground and 240VAC between them.

Now it kind of looks like the messenger cable is also the neutral conductor.

And look at the differences in cable ODs between what goes into the house and what comes from the utility pole. The pole wires must be 1/3rd the diameter of the larger cables on the left. I'd guess the nominal 240 volts must drop quite a bit when all the 240v house appliances are on.

Here's pics of bolt to bolt fasteners.

Use a threaded rod going into the house because the length required is probably unknown. The rod should go through roof structural members, not like how they appear to have done it in your photo.

I think you will find that is area is 2 ft below the attic space and the missing part was screwed in to sheeting behind the siding and would be better if it was screwed into the stud at the corner of the building. No?

Thanks all

How much (range/estimate) to hire a electrician contractor for this task?
And is angie's list good for finding them?

Does house insurance cover this? From natural storm Sandy......

Thanks again

It likely would not cost as much as your deductable. Good luck finding a contractor right now.

I am thinking claiming insurance because this is not the only damage. I have to go thru the insurance paper to get to know the detail. Here is two more pictures

1. Chimney cap blow off.
2. Vinyl (small issue, I can fix it myself)

Go over it with your broker, you also want to consider what it does to your premium in the future.

Inspect your roof. The chimney cap could have damaged it when it blew off.
