                            HUBBELL REPORTS STRONG

                            SECOND QUARTER RESULTS
                            ----------------------


ORANGE, CT.  (July 20, 2004) -- Hubbell Incorporated (NYSE:  HUBA, HUBB) today
reported strong results for the second quarter ended June 30, 2004.

Sales for the quarter were $502.9 million or a 12% increase over sales of $449.3
million reported for the corresponding period of 2003.  Net income was 30%
higher at $31.4 million and earnings per share increased by 28% to $.51 as
compared to $24.2 million and $.40, respectively, reported in the prior year.
Profit results in both periods included expenses under the company's continuing
restructuring programs of $10.4 million pre-tax in 2004 and $6.6 million
pre-tax in 2003.  The second quarter 2004 restructuring expense provided for a
factory closure in Hubbell Wiring Systems and ongoing restructuring in Hubbell's
Lighting businesses.

OPERATIONS REVIEW:
- -----------------

"Hubbell's second quarter results more than met our expectations," said Timothy
H. Powers, President and Chief Executive Officer, "in both the pace of recovery
in our markets, and the value of our strategic initiatives.  A second
consecutive quarter of double-digit sales increases reflects improving
conditions in our major markets.  Higher volume combined with the effectiveness
of the transformation of the operations yielded a 32% increase in operating
profit.  We're also pleased that each of our three segments reported higher
margins in the quarter with the consolidated operating margin up by 140 basis
points even after incurring $3.8 million pre-tax in incremental cost
associated with special charges."

                                  -continued-

"The cost of raw materials continued to present a significant challenge during
the quarter," Powers added.  "While costs have moderated on some materials, most
metals, freight, and energy costs are significantly higher than one year ago.
Steel costs are still volatile and show no signs of moderating.  Many of our
announced price increases took effect during the second quarter which partially
countered rising costs, but we remain concerned about the level and volatility
of these costs."

Year-to-date cash flow from operations of $79.6 million compares to $90.2
million in 2003 as higher net income was more than offset by higher working
capital to support sales growth.

SEGMENT REVIEW
- --------------

Sales for the Electrical Segment rose by more than 13% with operating margin up
by 150 basis points.  Within the segment, Hubbell's wiring systems businesses
reported higher sales due to improving factory maintenance and repair activity.
Hubbell Lighting also had a strong quarter as demand increased across a broad
array of markets.  Residential lighting fixture markets remained strong and
demand in commercial markets such as architectural, emergency and fluorescent
fixtures continued to strengthen.  Favorable sales and operating profit
comparisons were reported by Hubbell Electrical Products where higher sales of
products for harsh and hazardous and electrical rough-in applications countered
sluggishness in non-residential construction markets.

Hubbell Power Systems results continue to benefit from leading positions in
its core utility product markets and success in expanding into related
construction markets.  Domestic utility customers continued modestly higher
project and maintenance investments required by the growing activity in the
economy and stronger utility balance sheets.  Sales for the Segment increased
by 13% year-over-year and operating margin rose by 80 basis points to 9.5% as
higher sales volume and productivity gains added to profitability.



The Industrial Technology Segment reported a 6% decline in sales chiefly as a
result of weaker demand in markets for high voltage testing and
instrumentation.  However, improved results at businesses manufacturing
industrial controls and equipment and internal productivity programs
contributed to a 300 basis point increase in operating margin.

SUMMARY AND OUTLOOK
- -------------------

"We're particularly pleased with another confirmation of the effectiveness of
our strategic initiatives," said Powers.  "Even though we're still in the early
stages of these efforts, our results are testimony to the progress we're
making.  We're expanding our lean manufacturing effort internally as well as
involving suppliers and customers.  Our restructuring programs continue to be
executed on schedule and on budget.  The Hubbell 2006 Program - a multi-year
implementation of a single business system across the enterprise -- is moving
forward.  Most importantly, as we achieve our interim goals in these programs,
we're moving toward bolder, more demanding and more rewarding objectives."

"Looking ahead to the remainder of 2004, the strong results so far have raised
our expectations.  Revenue growth for the year should approximate 10-12% with
earnings per share, excluding restructuring costs, in the range of $2.35 --
$2.50."
