Service Entrance Size

GregS

Stupid question, does this look like a set of #3's on the service entrance? I'm skeerd to touch them to read the sheath

It looks like at least #4CU. Why do you ask if it is #3?

I remember when I spoke to the 'electrician' who did the service upgrade he said it was a #6.

I was reading the local code book stating it needs #3 for 100A. Just wanted a second opinion.


The ground is the other end of what was in this picture.. So you can understand my concerns.

and look at the markings on the neutral? Also #6 copper is only good for 65A (@75C)

That's old TW wire. That would be 60° wire.

It looks like it could be #3 to me, but if it's TW that's only good for 85 amps.
And if it's part of a multi-wire assembly you'll have to read the sheathing, there's likely nothing written on the wire

The ground wire is probably 6 wire.
My bet is that it is 2s.
Nobody around here ever even STOCKED 3 guage.

... but the real question is ...
why is the panel mounted sideways?

If the service panel was worth changing, why not the entrance cable?
....or is this a subpanel? ... then why is the neutral bar bonded to the enclosure?

Is that a cable connector or the end of a steel conduit [parallel conductor]? [that looks like a bushing and I don't remember ever seeing a black insulated ground in a cable ...]

... or don't the laws of physics apply north of the border?

Its a Main entrance not a sub-panel .Ground wire pluse bounding screw.And the reason why they put the panel in sleeping mode , its cause all the mains werent long enough so they put it sideways. Ive done it a few time no choice.

regid lock-nut with a reducer, broke one knock-out too many.
But in quebec, when u change a panel on an old service like this usualy the lock-nut has a ground lug on it, and its required to put it back.

Those look like #2's to me, and the GEC a #6.

I did not notice the date I was referring to Roger who always has great info, but I have not seen him in a while.

They look like 2's to me too. We have a whole spool of 2 at our tech shop.

They look like #3 copper to me, he missed the ground bushing on the service raceway BIG no-no as per the OESC. Looks like you have some old flat rate hot-water conductors in there too. wasn't any of this inspected??? Looks shady to me!

I would put money on #2 as well.
