TEST PROGRAM DESCRIPTION7.0

These tests consisted of three individual tests between parallel rigid steel.conduits and/orfree air cables mounted 1/4-inch apart'or in-contact at a point when crossing. For Test 1,the target cable was wrapped around the 1-inch conduit containing the faulted cable. ForTest 2, the target conduit was 1/4-inch above and parallel to the 3-inch fault conduit. Inaddition, a free air cable dropped 1/4-inch horizontally away from the fault conduit. ForTest 3, one target conduit touched the fault conduit, at a point, and the other target conduitran parallel with 1/4-inch horizontal separation.

7.1 Purposes

The purposes of these tests were to:

1. Demonstrate the acceptability of design where a control or instrumen-tation (low energy) conduit is in-contact with a raceway or cable requiringseparation (Test 1).

2..Demonstrate the acceptability of design where a rigid conduit passes 1/4-inch horizontally or vertically away from a rigid conduit containing theworst case power-type cable (Tests 2 and 3).

3. Demonstrate the acceptability of design where a free air cable isphysically separated by 1/4-inch horizontally from a rigid conduitcontaining the worst case power-type cable (Test 2).

4. Demonstrate the acceptability of design where a rigid conduit touches, at apoint, a second rigid conduit containing the worst case power-type cable(Test 3).

2 0 . TEST PROGRAM

2.1 Test Specimen Inspection

An inspection of the test specimen cables and conduits was performed prior to starting thetest program. This inspection verified that the specimens were as stated in Paragraph 6.0 ofthe Summary Section. Applicable manufacturer, part number, cable size, and cable B/Mnumber were recorded on a Test Specimen Inspection Sheet. The test specimens werelabeled with Quality Assurance "Test Specimen" tags to facQitate identification throughoutthe test program.

2.2 Test Specimen Preparation

- The test specimens were mounted into the test assemblies of Figures I-I, I-3, or I-5. Thisapparatus was manufactured to the indicated dimensions by Wyle technicians using materialssupplied by CPdcL. The following guidelines were observed with regard to the materials andconstruction of the test assembly:

1. The faulted cable was a 3-1/C 10 AWG cable for Test 1, and a Triplex350 MCM cable for Tests 2 and 3. This cable was mounted inside a 1-inchconduit for Test 1, or a 3-inch conduit for Tests 2 and 3.

2.

3y

The ends of the faulted cable were wrapped from their termination on thecopper bus bar to the edge of the test assembly. This wrap consisted of asingle layer of HAVEG SILTEMP WT-65 or 188 CH covered with a singlelayer of 3M No. 69 glass tape.. This wrapping was done as a safety measure'o ensure that any ignition that occurred was contained to the test area.

The target cable(s) was a Twisted Pair (T.P.) 16 AWG cable for all threetests. This cable(s) was mounted as described below:

c ~ Test Results

The test results are detailed in Wyle Test Report No.47879-02. The minimum separation distances based on thetest results are detailed in Table 8.3.1.10.

27Where conduit separation distances are detailed inTable 8.3.1.10, it applies to any enclosed raceway(i.e., conduit, box, equipment enclosure, condulet,fitting, etc.).

(2) ~anal sis - Where the damage potential is containedwithin a conduit, and the Class LE cable(s) are in tray orare free air drop out cable, an analysis has been performedin accordance with the recommendations of Section 5.1.1.2 ofIEEE-384-1974 to justify a minimum separation distance of oneinch. The results of the analysis indicate that providedone-inch separation is maintained, any damage potentialassociated with the conduit will have no adverse affects onthe Class LE circuits.

(3) Installation of Barriers - Where the separationdistances could not be justified by test or analysis suitablebarriers/or approved protective coatings have been utilized,

. or cables have been installed in enclosed raceways which aresuitable for protecting the cables. The minimum separationdistance between enclosed raceways or between barriers andthe raceway/cable(s) is one inch.

(b) Cable and Raceway Hazard Areas — AnaLyses of the effects ofpipe whip, jet impingement, missiles, fire, and floodingdemonstrate that safety related electrical 'circuits, raceways, andequipment are not degraded beyond an acceptable level.

The analyses are referenced as follows:

High, Pressure .Piping

Missiles

Flammable Material

Flooding

(Section 3e6)

(Section 3.5)

(Section 9.5.1)

(Section 2.4)

In fire hazard areas outside the cable spreading rooms, whereredundant safety related trays or safety related and non-safetyrelated trays are exposed to the same fire hazard, protection hasbeen provided by spatial separation, fire suppression systems,fire retardant coatings, fire barriers, or combination thereof.

8.3.1-40 Amendment No. 27

SERIAL: MLS-86-307

The following are suitable barriers to meet the intent of IEEE-380:

(a)

(b)

(c)

Steel Tra Covers - Tray covers are utilized to pr otect any raceway/cable whichconverges within the separation window of the tray. A top cover is used to protectabove the tray and/or a bottom cover is used to protect below the tray.

~Firewra - A cable is firewrapped to protect any raceway/cable which convergeswithin the separation window of the cable.

Fireblanket —One-hour and three-hour blankets are installed to meet therequirements of Section 9.5.1. These blankets are acceptable barriers.

Also, I inch of fireblanket is, also equivalent to I inch of air. Since fireblankets aregreater than I inch thick, separation is not required between blankets andprotected raceways.
