                          HUBBELL REPORTS FIRST QUARTER

                SALES UP 18%, EARNINGS OF $.65 PER DILUTED SHARE


ORANGE, CT. (April 20, 2006) -- Hubbell Incorporated (NYSE: HUBA, HUBB) today
reported first quarter earnings per share of $.65, an increase of 41% compared
to $.46 in the first quarter of 2005. Sales in the quarter were $573.0 million,
an increase of 18% compared to sales of $487.6 million reported in the first
quarter of 2005. Net income of $39.7 million was 38% higher compared to $28.8
million in the first quarter of 2005.

Year-over-year sales and profit comparisons for the quarter include pre-tax
expense of $2.7 million or $.03 per diluted share for stock-based compensation
for the first quarter of 2006, a pre-tax charge of $4.6 million or $.05 per
diluted share for transactional expenses in the first quarter of 2005, and the
impact of acquisitions completed in the second and third quarters of 2005 which
contributed 3 percentage points of the net sales increase and approximately $.02
of diluted earnings per share.

Cash flow from operations was $16.5 million compared to $1.1 million in the
first quarter of 2005 primarily due to overall higher net income. Capital
expenditures increased quarter-over-quarter primarily due to investments in new
products. In addition during the first quarter, the Company repurchased 760,000
shares of its stock for $32.9 million.


                                  -continued-

OPERATIONS REVIEW

"We are very pleased with our first quarter performance," said Timothy H.
Powers, Chairman, President, and Chief Executive Officer. "Most of Hubbell's
markets have been strong to start the year and our multi-year initiatives gained
traction. This was most apparent at the Power Systems and Industrial Technology
Segments where accomplishments in lean manufacturing, low cost sourcing, and
acquisitions leveraged positive trends in underlying markets.

"Positive market trends were also apparent in our Electrical Segment's markets,"
Powers added, "as sales rose by 11% and order input increased at an even greater
rate. As expected, and as we've noted in recent public presentations, the
Segment's margins were lower year-over-year principally in our Wiring Systems
and Lighting businesses resulting from production and delivery inefficiencies
and product outsourcing.

"Important for Hubbell's long-term growth was the third SAP implementation
completed in early April. Building on our experience in past `go-lives' -
especially the most recent success in the Lighting and Electrical Products
businesses - the Power Systems implementation is, thus far, working well. We now
have 75% of the Company `live' on the system. The final SAP implementation in
our domestic operations is scheduled for October 2006, at Industrial Technology
and the remaining Lighting operations."

SEGMENT REVIEW

Sales for the Electrical Segment were $391.1 million, an increase of 11% while
operating income was $31.4 million, comparable to last year. Each of the three
businesses in the Segment - Wiring Systems, Electrical Products and Lighting -
reported higher sales and double-digit rates of new order input. Each of the
three also reported steady progress in addressing specific issues that have
lowered profitability.

      -     At Wiring Systems, production and delivery inefficiencies are on
            track for resolution over the next several months. At the same time,
            the recently introduced metal raceway line has received good market
            acceptance and is ahead of plan for sales.

      -     Hubbell Lighting reported volume improvements in both its stock and
            project Commercial and Industrial fixtures businesses. All five
            regions of the country reported higher sales. Residential


                                  -continued-

            fixture volume was also positive year-over-year despite the housing
            market slowing moderately from its record pace of 2005. Business
            integration and streamlining activities continued to impact
            profitability in the quarter. Production transfers as well as office
            relocations have resulted in costs of duplicate facilities,
            increased logistics costs, and lower productivity levels. Production
            transfers are expected to be substantially completed by year-end
            2006.

      -     Hubbell Electrical Products continues to contend with material cost
            increases - steel prices increased again on April 1 - but these
            operations are effectively managing toward cost/price parity.
            Selective selling price increases and a focus on internal
            efficiencies and cost reductions are all contributing. The market
            for harsh and hazardous application products was especially strong
            during the quarter.

Sales for the Power Systems Segment rose by 34% to $132.3 million, operating
income nearly doubled to $20.5 million, and operating margin exceeded 15%.
Strong order input across all of the Segment's businesses reflected more robust
capital investments by the utility industry. Leveraging that volume growth into
substantially higher profitability was one of the Segment's operating
achievements. Lean manufacturing advances are helping to eliminate unnecessary
capacity internally while effective pricing actions to counter continued cost
increases remained in the forefront. The Segment's recent acquisition in Brazil
- - Delmar Manufacturing - also contributed to higher year-over-year sales and
operating profit.

The Industrial Technology Segment added another quarter of growth with sales of
$49.6 million up 40% and operating income of $8.7 million up by 78%. Every one
of the Segment's diverse businesses reported substantial increases in sales and
profit including two acquisitions completed in the second half of 2005 which
contributed approximately half of the sales increase. Particular strength was
noted in the offshore oil and energy markets and the global high voltage test
market. All are expected to exhibit continuing strength.

SUMMARY AND OUTLOOK

"The quarter exceeded our expectations throughout Hubbell's operations," Powers
added. "We anticipated lower margins in the first quarter in our Electrical
Segment as we began this year of peak investment and change. The Lighting
streamlining, a major new product introduction, and the domestic SAP
implementation


                                  -continued-

are expected to be substantially completed this year. Each requires considerable
investment in time and money. Each should prove to be well worth the effort.

"We also expected continued strength in markets served by Power Systems and
Industrial Technology, and that was the case. Both Segments are demonstrating
their operating efficiencies by reaching our interim strategic goal of 15%+
operating margins. Those results are testimony to the effectiveness of our
initiatives.

"While the economic environment is generally positive, and our programs are on
schedule, much remains to be done in 2006. We have a final domestic SAP
implementation, more Lighting streamlining, and continuing challenges in
material and energy costs. As a result, we are maintaining our full year 2006
earnings per share guidance in the range of $2.60 to $2.80."
