The problem with the picture is it does not show the installation in context with the entire area.

This is on the ceiling of a parking garage and IMO it sticks out like a sore thumb. I could not enter the side of the box as the other pipes where in the way. I could have / should have done this in a number of different ways.

Perhaps straight up from the rack 90 across the ceiling and 90 into the box.

This is more like the work I like to perform.

Re: Homeowner DIY

Bob, that is the type of work more fitting to you. :)

Just out of curriosity, will you grout or will you fire caulk these holes?

I have not decided yet, I am open to suggestions.

My feeling is that those holes are a bit big to use fire stop ($$$) on them there are 4 identical floors like this.

I have been leaning toward cement for the cost reasons.

I have other ares where 2" EMT is passing through these same size cores and in those areas I used intermesant fire stop.

Hey, I wish I could just holesaw floors all day too, Bob, but at the end of the day it just doesn't pay the bills. :eek:

Two I cut right out, luckily they where empty :cool: the third I just cut a small window in without damaging the conductors.

Normally we sub this work out but there are security issues in these buildings that make bringing in other people difficult.

Re: Homeowner DIY

Bob, I agree and would use grout myself.

Besides the expense asociated with Fire Caulk and packing materials, I think fire caulk looks tacky in this type of situation.

I say cement you say grout. :confused:

Is there a certain product you like to use.

When I hear grout I think of the stuff between tiles. Is that the thing to use as it flows better?

Around here I usually leave the fire stopping to the GC but there is no GC on this job.

Thanks for the help, Bob
 
Re: Homeowner DIY

By the way, I agree on the 'tackiness' factor.

These buildings even have the electric room floors vinyl tiled and they keep them clean and waxed.

Here is a conference room in the same building, thats not veneer on the walls that is solid Cherry.

Re: Homeowner DIY

Bob, I think it's just a regional slang difference. :)

I usually seal the bottom of the hole with some mineral wool, then use a mixture of Portland cement and a mortar or sand mix, it sets pretty fast and is easy to work around the penetrants.

That appears to be a Federal building.

We do FBI, GSA, Federal Marshal, Airport, and other security tight type work.

What I find amusing is the fact that we have to have security checks and clearance for each organization. ;)

Re: Homeowner DIY

We do some Govt. work also, however this is not.

I can not say who or what they do, only that this extravagance is a sin and they should be ashamed of themselves when they sit in this room.
 
Re: Homeowner DIY

Steelbuster,

Just wanted to say that the panel looks very good. Only concern would be the GEC in the conduit IF it were metalic conduit.

Bob just be honest, we know this is your dinning room. :D

No that is the TV room, notice the large screen and speakers on the far side.

This is one of my dinning rooms. :p

I notice only 4 settings... who is not invited? :) I hope I am not putting too much pressure on you ;)

BTW - I would myself have the penetrations cemented as well.

The GEC is required to be bonded to the enclosure if the enclosure is ferrous.

The reason I think it is unecessary (especially considering an inspector would think of tagging it for not liking the way it's done) is because of the fact, that anyone in the future that should be in this panel would know what the conductor is by looking at where it's landed.

If they didn't know what the conductor was, then they shouldn't be in this panel.

What if the conductors are disconnected in the future for, say, a panel replacement? You could argue that the conductors can be marked at that time, I suppose, but then why not apply the same logic to, say, the wires on a receptacle?

Besides, it has been my experience that conductors are pulled into conduit simultaneously, not one at a time. So how does one identify the unmarked end of a neutral (or any wire for that matter) after pulling? We ID conductors before pulling, and verify before energizing.

We sure do, but how many times is the original mark that you put on in the right place. :D

Do you mean did we mark them properly, or has the tape been damaged during the pull?
