Drawing types.

For Worldwide: KKE Circuit is available across Global in English. Region: Global (INT).

Schematic / control drawing (IEC 60617)

The Schematic drawing type is the workhorse of electrical documentation in KKE Circuit. It uses the IEC 60617 symbol library by default. Schematic drawings can be ladder-style (American convention) or geometric (European convention) — both are supported by the same drawing type; layout is a placement choice.

KKE Circuit specifics

• Page sizes: A0, A1, A2, A3, A4 (portrait or landscape).
• Reference designators: IEC by default (K, Q, F, M, T, X).
• Multi-sheet packages with automatic Sheet X of Y numbering.
• Cross-sheet net labels.

Single-Line Diagram (SLD)

KKE Circuit specifics

• Components rendered using their single-line variant automatically.
• Page sizes A3–A0 typical; A2 most common for substation SLDs.
• Bus bars supported as a first-class symbol.

Power drawing (3-phase, motor starters DOL / Star-Delta / VFD, switchgear, busbars)

Quick answer: A power drawing shows the three-phase power circuit explicitly — every phase as a separate conductor — including incoming supply, switchgear, busbars, motor starters, and outgoing feeders. KKE Circuit's power drawing type ships with DOL (direct on-line), Star-Delta, soft-starter and VFD starter macros that can be dropped onto the canvas as pre-wired blocks.

Starter type	Use when	Pre-wired macro
Direct on-line (DOL)	Small motors (< 7.5 kW) where inrush is acceptable	✅
Star-Delta	7.5–55 kW motors needing reduced starting current	✅
Soft starter	Smooth ramp-up, electronically controlled	✅
Variable Frequency Drive (VFD)	Speed control or energy efficiency	✅

Wiring drawing (with cable schedule)

A wiring drawing is the physically-laid-out counterpart to the schematic. KKE Circuit's wiring drawing type embeds a cable schedule at the bottom of the sheet that lists every cable: cable ID, source device, destination device, conductor count, cross-section, length.

Terminal drawing

A terminal drawing documents every terminal block in a panel. KKE Circuit auto-generates these from any wire that crosses a panel boundary. See "What is a terminal strip drawing?" in Core Concepts and "Terminal-strip auto-generation" in Calculations & Automation for the workflow.

PLC / I/O drawing (one rack per sheet, auto I/O list)

KKE Circuit specifics

• One PLC rack per sheet; multi-rack systems use multi-sheet drawings.
• Channel types: DI, DO, AI, AO, RTD, TC, HSC.
• Auto-generated I/O list embedded at the bottom of the sheet (or as a separate report).

Sensor connection drawing

A drawing focused on the wiring of field sensors back to the panel — proximity sensors, photoelectric sensors, RTDs, thermocouples, level switches, pressure transmitters. KKE Circuit's sensor connection drawing type understands 2-wire, 3-wire, 4-wire and 4-20 mA loop wiring.

Relay-board connection drawing

A drawing of the wiring between the panel's main control circuit and a separate relay board (interposing relays, safety relays, isolators).

Panel-to-panel interface drawing

Documents every wire and every cable that runs between separate panels in a system (main panel, sub-panels, MCCs, remote I/O cabinets). Cable type, conductor count, conductor cross-section, and source/destination terminal are shown. KKE Circuit can derive this drawing from the netlist when components are assigned to panels.

Earthing drawing

Documents the protective earth (PE) network of an installation: equipment grounding bonds, main earth bar, earth electrode, equipotential bonding, and the PE conductor sizing.

Incomer drawing

A drawing focused on the incoming supply: utility transformer, main MCCB, busbars, metering current transformers, voltage transformers, surge protection, neutral-earth bonding.

General arrangement (panel front view)

A scaled physical drawing of the panel's front face — every device rendered using its panel-front-view variant — showing the actual size and position of MCBs, contactors, terminal blocks, push-buttons, pilot lights and labels. Used for panel build and door layout.

P&ID — Process & Instrumentation Diagram (ISA-5.1 / ISO 10628)

The master schematic of a process plant. See "What is a P&ID?" in Core Concepts for the full definition and KKE Circuit's P&ID feature set.

Pneumatic schematic (ISO 1219)

ISO 1219 pneumatic symbols cover compressors, FRLs (filter-regulator-lubricator), 2/2 / 3/2 / 5/2 / 5/3 valves, single-acting and double-acting cylinders, flow controls, pilot-operated check valves, pressure regulators, mufflers.

Hydraulic schematic (ISO 1219)

Hydraulic schematic symbols cover pumps (gear, vane, piston, variable-displacement), reservoirs, filters, relief valves, directional control valves, pilot-operated check valves, accumulators, hydraulic motors, cylinders.
