                                 HUBBELL REPORTS

                              FIRST QUARTER RESULTS


ORANGE, CT. (April 20, 2004) -- Hubbell Incorporated (NYSE: HUBA, HUBB) today
reported its results of operations for the first quarter ended March 31, 2004.

Sales in the quarter were $465.2 million or an 11% increase over sales of $419.4
million reported for the corresponding period of 2003. Net income was $34.0
million and diluted earnings per share were $.56 as compared to $21.7 million
and $.36, respectively, in the prior year. Profit results in both periods
included expenses under the Company's on-going restructuring of Hubbell's
lighting businesses of $1.4 million pre-tax in 2004 and $1.1 million pre-tax in
2003.

OPERATIONS REVIEW:

"We are very pleased with these results," said Timothy H. Powers, President and
Chief Executive Officer, "with healthy sales increases year-over-year in each of
our three business segments. We also reported substantial improvements in
operating income margin in part due to the volume increase but also due to
productivity gains across all of our operations. We're in our third year of
transforming the Company, and we've cited the potential of these programs to
generate higher profitability when volume turns up. Operating income margins in
the first quarter were up significantly in each segment and up three points for
Hubbell in total."

"The biggest challenge during the quarter was rising raw material costs," Powers
added. "Steel, copper, nickel, aluminum and other commodity costs rose
significantly over the last six months. As a result, we've

                                  -continued-

announced price increases to partially counter the impact. The net impact of the
cost and price increases had only a small effect on the first quarter. The
greater impact on our costs and pricing will be seen in the second quarter and
the remainder of 2004."

SEGMENT REVIEW

Sales for the Electrical segment rose by more than 10% with operating margin up
by 260 basis points to nearly 11%. Hubbell's Wiring Systems businesses reported
increased sales from improving factory maintenance and repair activity. Hubbell
Lighting also had a strong quarter. Residential lighting fixture markets remain
very healthy with home construction up 13% year-over-year in the first quarter
and strong backlogs reported by national home builders. Demand in commercial
lighting fixture markets such as architectural, emergency, and fluorescent also
strengthened in the quarter. Hubbell's Lighting business generated nearly a 9%
increase in sales with margins up significantly. Favorable sales and profit
comparisons were also recorded by operations serving harsh and hazardous
applications and electrical rough-in products. The latter countered continued
sluggishness in non-residential construction markets with substantial gains in
the home center and do-it-yourself channels.

Hubbell Power Systems continued to aggressively build success in utility markets
with the Segment reporting an 11% gain in sales year-over-year. Modestly higher
project spending by domestic utility accounts, more economic optimism overseas,
and low inventories within distribution channels were positive influences. Also
contributing were higher sales of pole line hardware, cutouts and tools used for
power line maintenance, and an expanding line of cable accessory products. The
segment's operating margin rose to 12% in the quarter primarily as a result of
the higher sales and productivity gains. Also boosting margins was the completed
integration of a pole line hardware acquisition. Increased raw materials costs -
especially for metals which are a large component of Hubbell's utility products
- - may reduce margins in subsequent periods since price increases announced
during the quarter are not expected to completely offset the impact.

The Industrial Technology segment reported a 13% increase in sales with
operating margin exceeding 10%. Specialty communications products from the
GAI-Tronics operation were, again, the foundation for the segment's growth with
strong sales and profit advances. Similar sales increases were also reported at
the Industrial Controls, Gleason Reel, and High Voltage units which benefited
from higher industrial maintenance and repair activity and improving demand for
high voltage test and instrumentation equipment. Here, too, higher volume and
internal productivity were primary contributors to higher margins.

                                  -continued-

SUMMARY AND OUTLOOK

"We're particularly pleased with the effectiveness of our on-going
transformation of operations," said Powers. "We're still in the early stages of
several strategic initiatives. Our lean manufacturing efforts are expanding from
the plant floor to our suppliers and customers. The restructuring of Hubbell
Lighting continues to be on schedule and on budget. Likewise, our multiyear
implementation of a single business system across the enterprise is moving
forward and our continuing focus on asset efficiency continues to generate
results. We have a lot of opportunity still in front of us, but we continue to
make progress."

"The first quarter was stronger than we expected. As a result, we are raising
our full year projection for sales to increase 4-8% year-over-year and earnings
per share in a range of $2.15 - $2.40 before an estimated $.15 - .25 of
restructuring expenses."

"As we've noted in recent months, about 70% of our products are sold to markets
that are bottoming or showing a positive trend. That bodes well for renewed
growth later in 2004 and in 2005."

"We are cautiously optimistic about the remainder of 2004. However, commodity
costs are high and volatile. It's difficult to forecast whether these costs will
continue to increase or begin to decline, and at what rate. The amount of
realization of recent price increases across the industry is still uncertain.
And the question remains whether the increase in activity in our markets will be
sustained for the remainder of the year."
