When pulling cables through a conduit,
what, if any, sort of lube do you use?
What is the best sort of Lube?.

I use either a product called yellow 77 or polywater. Both work just fine cost is the deciding factor most of the time.

we use a product called "aqua-gel". seems to work better than the old "yellow-77", and evaporates rather than getting sticky and "gluey" like the yellow-77. i have had to pull out cables such as MCM 250-500 before, that had been originally pulled with yellow-77, and they were stuck inside the pipe like super-glue, sometimes, nearly ripping the conduit down, just to get them to budge a little.

Ideal makes a non freezing lube,(agua gel?) but the claim is like 30 degrees. Not much help in No New England, especially this year it seems [Linked Image]. Mighty chilly already.

NEC Rule in Article 517:

"Wire-pulling compounds that increase the dielectric constant shall not be used on the secondary conductors of the isolated power supply." www.nfpa.org

Don't ever use axel grease!!!

The last hospital isolated power system that I worked on required the use of XHHW wires and only talc for lube if needed. This was in the design specs for the job.

Is talc allowed everywhere? I've never heard of using it as a pulling lube before. But I do remember being the young aprentice standing under the conduit and getting a shower of yellow goo.

A few more years of therapy and I should be ofer it. [Linked Image]~

WIRE-PULLING COMPOUNDS (ZOKZ)

Wire-pulling compounds are for use as lubricants in installing electrical
conductors in raceways. Listed compounds have been investigated to determine their compatibility with conductor insulation and coverings.

The Listing Mark of Underwriters Laboratories Inc. on the product is the
only method provided by UL to identify products manufactured under its
Listing and Follow-Up Service. The Listing Mark for these products
includes the UL symbol (as illustrated in the Introduction of this Direc-tory)
together with the word ²LISTED,² a control number, and the product
name ‘‘Wire Pulling Compound’’ .

Here is part of the installation instructions from the PostGlover website. They are a manufacturer of hospital isolated power systems.
Quote
All Branch Circuit Conductors of the isolated power system shall be stranded copper having a cross-linked polyethylene insulation, or equivalent with a dielectric constant of 3.5 or less. Type XHHW is suitable for this purpose. Each branch circuit conductor shall be color-coded in accordance with National Electrical Code. Wire pulling compound produces an adverse effect upon the dielectric constant of conductor insulation and shall not be used when pulling the wire of the isolated power system. Use of dry talcum powder is permitted.
