Elbows

Sentron B usw ay elbow s provide a sim -ple, convenient m ethod of changing the

direction (left, right, up or dow n) of a

busw ay run. All elbow s are shipped w itha joint stack assem bly on one end for

direct connection to the busw ay system .

Flatw ise elbow s are used for left and

right directional changes w hen thebusw ay system is m ounted in the

horizontal plane; bus bars run parallel to

the floor. The nam eplate (N P)lies on theneutral side of flatw ise elbow s, w hich is

the side of the elbow that faces the floor.

The joint stack assem bly m ay be m ovedto the opposite leg to change the orienta-

tion from left to right/right to left.

Edgew ise elbow s create up and dow n

directional changes. The nam eplate andneutral side lie on the outside of the bend

for edge up elbow s. The nam eplate and

neutral side lie on the inside of the bendfor edge dow n elbow s. The joint stack

assem bly on edgew ise elbow s can not

be m oved in order to change orientationfrom up to dow n/dow n to up.

For both edgew ise and flatw ise elbow s

the sum of the tw o legs m ay not exceed

10 ft. (3.05m ). See draw ings for m inim umdim ensions. C ustom lengths available.

Tees

Tees are used to sim plify directional andplane orientation changes in a busw ay

system . Tees can m ake 90 bends left

or right, and up and dow n along thebusw ay run. All tees are supplied w ith

tw o joint stack assem blies.

Flatw ise tees are used to create left

and right branches. The nam eplate (N P)lies on the neutral side of the tee.

Edgew ise tees are used to createbranches that stem up or dow n from

the busw ay run. The nam eplate and

neutral side lie tow ard the floor on edgedow n tees w hile the nam eplate and

neutral side lie tow ard the ceiling on edgeup tees. Edgew ise tees are housed in a

special box enclosure to provide rigidity

and shield against dirt and dust.

Center Tap Boxes

Center tap boxes are non-fusible devices

utilized to feed to or take off pow er from

the busw ay run. W hen loads served by

the busw ay run do not require over-cur-rent protection, center tap boxes m ay be

used. If the application requires additionalw iring bending space, extended center

tap boxes are available. Center tap boxes

are an actual part of the busw ay run andrequire a space of 32 in. (810m m ) for

installation. O ne joint stack assem bly isprovided w ith each center tap box.

Service Heads

Service H eads are used to connect

busw ay to a service entrance. In the

Sentron Busw ay line, 3-single phase

service heads and 3-phase service headconnections are available. The standard

service entrance connection is the3-phase service head w hich consists of

one service head for all three phases.

3-single phase service heads consist ofthree heads one for each phase and

m ay be used to m eet the requirem ents ofcertain applications. To ensure ease of

installation of incom ing cables, both types

of Sentron service heads are constructedso that the lugs face the G lastic bottom

of the box. The G lastic bottom provides

insulation and protection to the incom ingcables.

m etering stacks, m ain disconnects are

available if the system reaches the 6 circuit

rule (see m etering bulletin for further

Panelboards are installed at special

engineered joint stacks and are pre-

End Closures

End closures safely term inate a busw ay

run and protect the bus bar ends. End clo-

sures m ay be rem oved easily in order to

extend a busw ay run. End closures areshipped w ith G lastic insulation pieces,how ever, joint stacks and inspection cov-

installation refer to end closure installationsheet shipped w ith each end closure.

Flanges

Roof, w all and floor flanges are available

for Sentron B usw ay. W hen the busw ay

run passes thorough a roof, w all or ceil-ing, a flange should be used. Flanges do

not offer support to the busw ay, only a

m eans of covering the hole created in theexisting structure. An additional sealant

m ay be required to m eet fire codes and

all other local requirem ents; no caulkingor gasketing is provided w ith S entron

flanges. Roof flanges provide a w atertightseal for use w ith IP65/ IP66 rated

busw ay. Roof pitch m ust be indicated on
