Found in a basement under the streets of Buffalo, NY where the salt has caused this corrosion:




This is currently being replaced with new equipment.

NEC Section 300.6 is a good read, check it out!

Joe,


I do a lot of old homes in the Buff, so to speak. What street was that one on.

Adam:


I believe it was located downtown in one of the commercial properties.

One of my students gave me a few images during our show and tell discussions when I was in Buffalo a few weeks ago.

Do you look for any items that fall within this subject? ![icon_question.gif](upload://t2zemjDOQRADd4xSC3xOot86t0m.gif)

300.6 Protection Against Corrosion.

Metal raceways, cable trays, cablebus, auxiliary gutters, cable armor, boxes, cable sheathing, cabinets, elbows, couplings, fittings, supports, and support hardware shall be of materials suitable for the environment in which they are to be installed.

Section 300.6 applies generally. For specific applications, see the particular article covering the appropriate cables, raceways, or enclosures.

(A) General. Ferrous raceways, cable trays, cablebus, auxiliary gutters, cable armor, boxes, cable sheathing, cabinets, metal elbows, couplings, fittings, supports, and support hardware shall be suitably protected against corrosion inside and outside (except threads at joints) by a coating of approved corrosion-resistant material such as zinc, cadmium, or enamel. Where protected from corrosion solely by enamel, they shall not be used outdoors or in wet locations as described in 300.6(C). Where boxes or cabinets have an approved system of organic coatings and are marked ?Raintight,? ?Rainproof,? or ?Outdoor Type,? they shall be permitted outdoors. Where corrosion protection is necessary and the conduit is threaded in the field, the threads shall be coated with an approved electrically conductive, corrosion-resistant compound.

Zinc chromate paste is one type of electrically conductive compound that could be approved.

Yeah Joe,


I look for it and put it in the report. I spent as many as 8-10 hours on a few of the reports for some of those properties. Grueling.

The detail i try to include in my reports goes far to drive me nuts when i have some of those 100 plus year old homes you have depicted in your photo.

I didn't know you were in town that recently. I would have tried to make it but i've been buried with work, more or less, since mid February. Most days i'm even eating on my lap in front of the computer or while driving. I'll look for you next time around. Any idea when that might be? (Roughly)

Joe,


the calendar on my site is a feature within Webstudio 4.0 that uses javascript to keep the image updated with the current date.


here is the html, good luck. In webstudio it is just a drag and drop thing that is really easy.

Thanks Ben!


Great shots of some common hazards. I have some images from Tijuana that look the same. ![icon_rolleyes.gif](upload://iqxt7ABYC2TEBomNkCmZARIrQr6.gif)
