      Re:  Franklin Custodian Funds - Registration Statement on Form N-14
           (FILE NO. 333-152780)

Dear Mr. Grzewskiewicz and Ms. DiAngelo:

      We are responding to your comments, provided via telephone on August 19,
2008 and August 20, 2008, to the above-captioned registration statement (the
"Registration Statement") filed by Franklin Custodian Funds (the "Trust") on
August 5, 2008. Each of your comments and our responses thereto are set forth
below.

      In connection with our responses to your comments, we acknowledge, on
behalf of the Trust, that:

o   The Trust is responsible for the adequacy and accuracy of
    the disclosure in the Registration Statement;
o   Staff comments to or changes to disclosure in response to Staff comments
    to the Registration Statement do not foreclose the Securities and Exchange
    Commission ("SEC") from taking any action with respect to the Registration
    Statement; and
o   The Trust may not assert Staff comments as a defense in any proceeding
    initiated by the SEC under the federal securities laws of the United
    States with respect to the Registration Statement.


1.    WHERE THERE IS A DISCUSSION OF THE REORGANIZATION COSTS, ADD SPECIFIC
      INFORMATION ABOUT THE PERCENTAGE OF THE COSTS BORNE BY THE FUNDS AND THE
      ADVISER AND THE TOTAL DOLLAR AMOUNT OF THE REORGANIZATION COST FOR EACH
      TRANSACTION.

      RESPONSE:  We have revised the discussions of the costs of
      the Transactions under the headings, "How will the
      Transactions affect me?" and "Who will pay the expenses of
      the Transactions?" to read as follows:

      FSS, on behalf of each respective Target Fund, will pay 25% of the
      expenses resulting from that Target Fund's participation in a Transaction,
      including the costs of the proxy solicitation. The Acquiring Trust, on
      behalf of DynaTech Fund, will pay 25% of such expenses for each
      Transaction. The total amount of such expenses for the Transaction with
      Technology Fund is estimated to be $90,078. The total amount of such
      expenses for the Transaction with Health Care Fund is estimated to be
      $108,057. The total amount of such expenses of the Transaction for
      Communications Fund is estimated to be $138,000.

2.    WITH REGARD TO THE EXPENSE EXAMPLE FOR HEALTH CARE FUND'S CLASS A
      SHARES FOR THE 10-YEAR PERIOD, PLEASE CONFIRM OR CORRECT THE NUMBER SHOWN.

      RESPONSE:  We have corrected the number shown.  It now reads
      $1,946.

3.    PLEASE CONFIRM THAT THE EXPENSE NUMBERS FOR ALL TABLES REFLECT THE
      RESPECTIVE FUND'S MOST RECENT AUDITED FINANCIALS.

      RESPONSE:  Confirmed.

4.    PLEASE MODIFY THE THIRD ASSUMPTION IN THE EXAMPLE ACCOMPANYING THE
      FEE TABLE FOR THE FUNDS, WHICH STATES THAT THE FUND'S OPERATING EXPENSES
      REMAIN THE SAME, SO THAT IT REFLECTS THAT THE EXPENSES TAKE INTO ACCOUNT
      ANY CONTRACTUAL WAIVERS FOR THE APPLICABLE PERIOD.

      RESPONSE: We have modified the third assumption to read, "The Fund's
      operating expenses remain the same, taking into account any contractual
      waivers for the applicable period."

5.    IN THE CAPITALIZATION TABLE, DISCLOSE THE DOLLAR AMOUNT OF THE
      REORGANIZATION COSTS TO BE BORNE BY THE FUNDS.

      RESPONSE: We have added the estimated costs of the Transaction(s) to be
      borne by the Funds to the footnotes to the pro forma columns of the
      capitalization table as follows:

      [Note 2:] Numbers are projected after the Transactions. The projected
      capitalization of DynaTech Fund after the Transactions with Target Funds
      includes the costs of the Transactions that will be borne by the Target
      Funds and DynaTech Fund, which are estimated to be $168,068 and which
      would be allocated to the share classes as follows: Class A: $137,375,
      Class B: $6,251, Class C: $22,602, Class R: $1,304, and Advisor Class:
      $536.

      [Note 3:] Numbers are projected after the Transactions with Technology
      Fund and Communications Fund. The projected capitalization of DynaTech
      Fund after the Transactions with Technology Fund and Communications Fund
      includes the costs of the Transactions that will be borne by Technology
      Fund, Communications Fund, and DynaTech Fund, which are estimated to be
      $114,039, and which would be allocated to the share classes as follows:
      Class A: $94,970, Class B: $3,470, Class C: $14,106, Class R: $1,058, and
      Advisor Class: $435.

6.    IN THE PRO FORMA FINANCIAL STATEMENTS, ADD DISCLOSURE THAT ALL OF THE
      INVESTMENTS OF THE TARGET FUNDS COMPLY WITH THE INVESTMENT RESTRICTIONS OF
      THE ACQUIRING FUNDS.

      RESPONSE: The requested language is already included in note 3 of the
      Notes to Pro Forma Combining Financial Statements (Unaudited). That note
      states as follows: "None of the securities held by the Franklin Technology
      Fund, the Global Communications Fund and the Franklin Global Health Care
      Fund as of the closing date will violate the investment restrictions of
      the Franklin DynaTech Fund."

7.    IN THE PRO FORMA FINANCIAL STATEMENTS, ADD A BRIEF DISCUSSION OF THE
      REORGANIZATION COSTS, INCLUDING THE PERCENTAGES AND TOTAL DOLLAR AMOUNTS.

      RESPONSE:  We have added the following to the Notes to Pro
      Forma Combining Financial Statements (Unaudited):

      6. REORGANIZATION COSTS

      The Franklin Technology Fund, the Franklin Global Health Care Fund, and
      the Franklin Global Communications Fund will each pay 25% of their
      respective expenses, including the costs of proxy solicitation, resulting
      from their participation in a reorganization. The Franklin DynaTech Fund
      will pay 25% of such expenses for each reorganization. FAI will pay the
      remaining 50% of such expenses for each reorganization. The total amount
      of such expenses for the reorganization of the Franklin Technology Fund is
      estimated to be $90,078. The total amount of such expenses for the
      reorganization of the Franklin Global Health Care Fund is estimated to be
      $108,057. The total amount of such expenses for the reorganization of the
      Franklin Global Communications Fund is estimated to be $138,000.

8.    IN THE PRO FORMA FINANCIAL STATEMENTS, ADD DISCLOSURE REGARDING THE
      TAX-FREE STATUS OF THE REORGANIZATIONS.

      RESPONSE: The requested language is already included in Note 1 of the
      Notes to Pro Forma Combining Financial Statements (Unaudited). That note
      includes the following language: "Each reorganization will be accounted
      for by the method of accounting for tax-free business combinations of
      investment companies."
