B146T&B FIT TINGS INDUSTRIAL FIT TINGS—Armoured cable and flexible metal conduit fittingsSpecifications – Armoured cableArmoured cable (Type AC90) Ref. CEC Rule 12-600The Canadian Electric Code 2012 Part I definestype AC armoured cable as, “A fabricated assemblyof insulated conductors in a flexible metallicenclosure.”All armoured cables may employ copper oraluminum or copperclad aluminum conductorswith the following sizes and are rated for 600volts or less: No. 14 AWG to no. 1 AWG copper No. 12 AWG to no. 1 AWG aluminum orcopperclad aluminumArmoured cable can be used for both exposedand concealed locations.Armoured cable is not permitted in locations whereit will be subjected to physical damage or corrosivefumes. Armoured cable cannot be used for directburial in earth.Codes require that cable shall be supported withstraps or staples without damaging conductors.Certain precautions are prescribed in code wherecable is installed through joist rafters or similarwood members.According to CEC Rule 12-610(1) Where conductors issue from armour, they shallbe protected from abrasion by bushings ofinsulating material or equivalent devices.(2) Where conductors are no. 8 AWG or larger,copper or aluminum, such protection shallconsist of: (a) Insulated type bushings, unless theequipment is equipped with a hubhaving a smoothly rounded throat; or (b) Insulating material fastened securely inplace which will separate the conductorsfrom armoured cable fittings and affordadequate resistance to mechanical injury.(3) Where armoured cable is fastened to equipment,the conductor or clamp shall be of such designas to leave the insulating bushing or itsequivalent visible for inspection.(4) Where conductors connected to open wiringissue from the ends of armouring, they shall beprotected with boxes or with fittings having aseparately bushed hole for each conductor.Please refer to the following for further detailsand complete information:1.

CEC Rule 12-1000Flexible metal conduit can be used for exposed orconcealed work in dry locations. It can be used forwet locations, provided conductors within are leadcovered or other approved type.Flexible metal conduit cannot be used undergroundor embedded in poured concrete or aggregate.With rubber covered conductors, the conduitcannot be exposed to oil, gasoline or othermaterials having a deteriorating effect on rubber.With minor exceptions, use of flexible metal conduitis not permitted in hoists, in storage battery roomsor in any hazardous locations. Use of flexible metalconduit is restricted to systems under 600 volts.Flexible metal conduit longer than six feet ispermitted to be used as a grounding meansprovided the conduit and the fitting are approvedfor the purpose. To date there is no flexible metalconduit approved for the purpose by theUnderwriters Laboratories or CSA.In Class II Zone 2 and Division 2 hazardous areas,the conduit itself cannot be used as the groundingmeans. Class I Zone 2 flexible connections at motorterminals and similar places, ref.: CEC Rule 18-152(6) and bonding CEC Rule 18-074 (1)(a). Class IDivision 2, flexible connections at motor terminalsand similar places, ref: CEC Rule J18-152 (3) andbonding CEC Rule J18-072 (1)(a). Flexible metalconduit is available with steel or aluminum armourin trade size 5 16 in. to 4 in. With few exceptionswhere 5 16 in. and 3 8 in. trade sizes are used, codeprohibits use of conduit less than 1 2 in. trade size.Bends in concealed work are restricted to four 90 bends (CEC Rule 12-940). No angle fittings arepermitted in concealed raceway installations.Please refer to the following for further detailsand complete information:1.
