SUMMARY OF FINDINGS

     During 1995, the total value of shipments of switchgear and switchboard apparatus was $6.0 billion, up 5 percent from the 1994 value of $5.7 billion.
The 1995 shipments include power circuit breakers valued at $427.1 million, a decrease of 23 percent from 1994; low voltage panelboards, valued at $2.0 billion,
an increase of 14 percent from 1994; fuses and  fuse equipment, valued at $423.3 million, an increase of 11 percent from 1994; molded case circuit breakers, valued at
$1.2 billion, an increase of 4 percent from 1994; duct, valued at $239.4 million, an increase of 5 percent from 1994; and switchgear valued at $1.7 billion,
an increase of 4 percent from 1994.  During 1995, the total value of shipments of relays and industrial controls was $8.6 billion, up 9 percent from the 1994 value
of $7.9 billion.  The 1995 shipments include general-purpose relays valued at $741.7 million, a decrease of 8 percent from 1994; specific-purpose industrial
controls, valued at $3.2 billion, an increase of 16 percent from 1994; general-purpose industrial controls, valued at $4.2 billion, an increase of 10 percent
from 1994; and motor controller accesories valued at $498.5 million, a decrease of 3 percent, from 1994.
