       Dear David S. Schulz:

              We have reviewed your July 10, 2023 response to our comment
letter and have the
       following comments. In some of our comments, we may ask you to provide
us with information
       so we may better understand your disclosure.

               Please respond to these comments by providing the requested
information or advise us as
       soon as possible when you will respond. If you do not believe our
comments apply to your facts
       and circumstances, please tell us why in your response.

              After reviewing your response to these comments, we may have
additional comments.
       Unless we note otherwise, our references to prior comments are to

   1.                                                   We note your response
to comment one and your proposed revised disclosure. Please
                                                        revise to quantify
expense amounts by segment and to provide separate discussion and
                                                        analysis for each
segment, rather than quantifying only the change in the expense amounts
                                                        and discussing them
together. Please consider whether presenting segment results in
                                                        tabular form, organized
by reportable segment, would aid financial statement users, with
                                                        narrative text
refocused on discussing and analyzing results in the tables rather than on
                                                        stating amounts in
tables.

2.       We note your response to comment two and your revised explanation of
value-driven
         pricing. If correct, consider whether a plain English description as
"price increases"
         would be more appropriate. In addition, the explanation of
value-driven pricing (or "price
         increases") appears to be a factor driving changes in sales rather
than cost of sales directly.
3.       We note your response to comment three and your proposed revised
disclosure. In your
         response you state you cannot precisely quantify the impact that
changes in prices or
         volume had on the change in net sales. However, in your fourth quarter
2022 earnings
         call, you stated:

                you estimate pricing added approximately 6 points to sales
growth, with the benefit
              primarily in your UBS and EES businesses (8% for the year);
                your ability to cross-sell Wesco and Anixter products and
services contributed more
              than $260 million of sales in the quarter ($850 million for the
year); and
                higher supplier volume rebates in the quarter provided a
40-basis-point benefit.

         Please reconcile these disclosures with your response. In your filing
you disclose that net
         sales increased primarily due to "price inflation and volume growth,
secular demand
         trends, and execution of our cross-sell program." Please tell us how
you know these were
         the primary factors affecting your results. We also note that you
disclose pricing "related
         to inflation" impacted net sales by 8%. Please tell us whether this
factor includes the
         effect of all pricing changes on net sales or just a portion
attributable to inflation. If it
         includes all pricing changes, please tell us why you are unable to
quantify this factor in
         absolute dollars nor compute the remaining change (after other
quantified factors) due to
         volume. If it does not include all pricing changes, please tell us how
you were able to
         measure or estimate this portion of the change in price but not other
portions, and how this
         portion is measured.
         Please direct any questions to Amy Geddes at 202-551-3304 or Lyn Shenk
at 202-551-
3380.
