MCC Schedule
Template (Excel)

An MCC schedule (Motor Control Center schedule), also called an MCC feeder schedule, is the EPC register of every feeder position in every low-voltage motor control center on a project. For each feeder it records the MCC tag, location, incomer source, bus rating, feeder position number, feeder tag, consumer tag (motor, heater, distribution board), motor rated power, full load current, starter type (DOL, star-delta, soft starter, VFD), switchgear type and rating, overload setting, cable number and size, voltage drop, hazardous area classification, control source, interlock reference, and spare position flag per IEC 61439-1 and IEC 61439-2 (low-voltage switchgear and controlgear assemblies).

Required columns: MCC tag, location, incomer source (transformer tag or upstream switchgear), bus rating in amperes and voltage (typically 415 V or 690 V for LV MCCs in India and the GCC), short circuit withstand in kA for 1 second per IEC 61439-1, form of internal separation per IEC 61439-2 (Form 1 to Form 4b), feeder position number, feeder tag, consumer tag, motor rated power, full load current, starter type, switchgear type per IEC 60947, overload setting and class per IEC 60947-4-1, cable number cross-referenced to the cable schedule, cable size per IEC 60502, voltage drop, hazardous area class per IEC 60079, control source, interlock reference, and spare position flag. The template covers all required columns.

Pathnovo, an engineering document intelligence platform, extracts every motor and electrical consumer tag from the motor list and electrical load list, parses the single-line diagrams (SLDs) to identify the MCC and feeder position per consumer, and pulls starter type, switchgear rating, and cable size from the SLD legend and per-feeder details. Hazardous area classification flows from the P&ID and area classification drawing. Typical project turnaround is 48 hours for the initial MCC schedule with 99.5% contractual accuracy. See the P&ID extraction workflow.

The motor list is the master register of every motor on the project (one row per motor, capturing motor-side attributes: rated power, voltage, frequency, frame, IP, IE class, hazardous area, vendor). The MCC schedule is the switchgear-side register (one row per feeder position, capturing the upstream switchgear, starter, cable, and control architecture for each consumer). One motor in the motor list maps to one feeder in the MCC schedule. The two registers are joined on the consumer tag. Both registers must be revision-aligned. See the motor list template and the electrical load list template.

Variable frequency drive (VFD) feeders are flagged in the Starter Type column with VFD; the switchgear position holds the VFD unit (typically a dedicated cubicle per drive) rather than a conventional starter, and the cable is shielded VFD cable per IEC 60502-2 specifications. Soft starter feeders (used for medium-sized motors to limit inrush) are flagged with Soft Starter; the cubicle holds the soft starter alongside a bypass contactor. Both VFD and soft starter feeders carry harmonic and EMC implications that flow into the upstream transformer sizing and filter sizing, and these are referenced in the Notes column.

On Indian PSU projects (IOCL, BPCL, HPCL, GAIL, ONGC, NTPC, NHPC, SAIL) and GCC projects (Saudi Aramco, ADNOC, QatarEnergy, KOC, Bapco, PDO) the MCC schedule is reviewed at IFC gate and is the basis for the LV switchgear procurement and the substation panel layout. Indian projects follow IS / IEC 61439 (harmonised standard) with CPRI type-test certification; GCC projects typically follow IEC 61439 with KEMA or DEKRA type-test certification. Hazardous area equipment certification follows PESO (India) and ARAMCO 17-SAMSS-502 or ADNOC 17-CEDP-08 style specifications. See the electrical load list template.

Downstream consumers: MCC tender package and material requisition (one MR per MCC, with feeder-by-feeder schedule appended), cable schedule generation (one cable per power feeder), cable tray and cable routing design, substation panel layout, protection coordination study (short circuit and discrimination per IEC 60909 and IEC 60364), earthing and bonding scope, hazardous area equipment certificate register, and pre-commissioning megger and continuity test record. The MCC schedule is revision-aligned with the SLD throughout the design and commissioning phase. See the cable schedule template and the motor list template.
