Installation Instruction Sheet
To order a 15/25 kV Class BOL-T Connector Kit, see following Steps
1-5 to build the catalog number.
BOL-T connector kit – catalog numbering system
Build the 12 digit catalog number for a BOL-T Kit by following the
steps given below. The first 5 digits are “BT625”, so only digits 6
through 12 need to be selected.
Catalog number digits:
1 & 2 = “BT”, BOL-T Connector System
3 = “6”, 600 A System
4 & 5 = “25”, 25 kV Class Bushing Interface
Step 1 – Select digits 6 and 7 cable adapter range code
Determine the cable’s diameter over the electrical insulation as
shown in Figure 4 (including tolerances).
Then identify a cable range from Table 3 that covers the minimum
and maximum insulation diameters.
Select the correct CABLE RANGE CODE from Table 3.
Step 2 – Select digits 8 and 9 conductor code
Identify the conductor size and type in Table 4 and select the
CONDUCTOR CODE from the appropriate (compression or shear
bolt) column.
Step 3 – Select digit 10
Determine whether Aluminum or Copper is required for the
compression connector, stud, and deadbreak insulating plug. Shear
bolt connector is only available as a 600 A aluminum connector.
“A” = Aluminum (Shear Bolt or Compression Connector)
“C” = Copper (Coppertop for the connector) Required to achieve
900 A rating, compression connector only.
Step 4 – Select digit 11
Determine if a stud should be included in the kit.
“1” = Stud Included
“2” = Stud Not Included
Step 5 – Select digit 12
Determine if the T-body should have a test point.
T = Test Point on T-body
If no test point is required, do not include an 12th digit.
EXAMPLE: Select a BOL-T Kit for 250 kcmil compressed cable with
a nominal insulation diameter of 1.160" ± 0.030". The kit should have
aluminum current-carrying parts and should have a stud included.
The T- Body should have a test point.
Step 1 – Select digits 6 and 7
Nominal diameter over insulation is 1.160" ± 0.030".
Minimum diameter = 1.160" - 0.030" = 1.130".
Maximum diameter = 1.160" + 0.030" = 1.190".
From Table 3, identify the cable range that covers 1.130" - 1.190" and
select the “EE” cable range code.
Step 2 – Select digits 8 and 9
The conductor size is 250 kcmil compressed. From Table 4, under
the column “Concentric or Compressed,” identify
250 kcmil and select the “17” conductor code.
Step 3 – Select digit 10
The kit should have aluminum current-carrying parts. Select an “A”
for digit 10.
Step 4 – Select digit 11
The kit should include a stud, so select 1 for digit 11.
Step 5 – Select digit 12
A test point is needed, so use a “T” for digit 12.
