Electrical and Installation Guides Page 10: 257 technical guides for choosing Electrical and Installation products: selection criteria, standards, common mistakes and frequently asked questions.
CEE Industrial Extension Sockets Selection Guide — When selecting IEC 60309 CEE extension sockets, compare 16 A–125 A current, 3/4/5 poles, blue (230 V) vs red (400 V) coding, hinged cover and IP44/IP67 protection. CEE Panel and Appliance Inlet Plugs Selection Guide — When selecting CEE panel and appliance inlet plugs, compare 16 A–125 A rating, 3/4/5 poles, surface vs flange mounting and mating with female extension sockets. CEE Angled Wall and Surface Sockets Selection Guide — A CEE angled wall socket is a CEE standard industrial socket that is surface-mounted on a wall with its own box, with the socket opening angled downward. CEE Straight Panel Sockets Selection Guide — The values given in parentheses in TP Elektrik product names, such as 70x70 and 83x90, indicate the flange size. CEE Industrial Extension Plugs Selection Guide — When selecting IEC 60309 CEE extension plugs, compare 16 A–125 A current, 3/4/5 poles, blue (230 V) vs red (400 V) voltage coding and IP44/IP67 sealing. Multi-Contact Industrial Sockets Selection Guide — A multi-contact socket is not a power strip that supplies several plugs; it is the female half of a single multi-core connection. Multi-Contact Connector Housings Selection Guide — It is used to protect the insert against impact, dust and water and to fix the connector to the end of a cable, a machine sheet or a panel surface. Panel Accessories Selection Guide — When selecting panel accessories, compare DIN rails, busbar insulators, fan filters & thermostats, gland plates, document pockets and lock/hinge compatibility. Standard Heat-Shrink Sleeves Selection Guide — When selecting standard heat-shrink sleeves, compare expanded vs recovered inner diameter (mm), 2:1 or 3:1 shrink ratio, wall thickness and color coding. Switch and Socket Frames Selection Guide — When selecting switch and socket frames, verify brand/series compatibility, 1-gang to 6-gang module count, horizontal vs vertical orientation and mechanism pairing. Socket-Mounted Combination Boxes Selection Guide — When selecting a socket-mounted combination box, compare 16 A–63 A CEE industrial socket layout, DIN-rail window module capacity and IP44/IP65 enclosure protection. Industrial Extension Cords Selection Guide — How to choose single-phase rubber and three-phase CEE 16A/32A industrial extension cords by conductor cross-section, length, and IP44/IP67 rating. Cable Terminals, Lugs and Ferrules Selection Guide — Selection criteria for wire ferrules, copper and bimetal cable lugs, insulated/non-insulated ring and fork terminals, faston connectors and splice sleeves. Industrial Plugs and Sockets Selection Guide — They are used in factories, workshops, construction sites, farms and stage setups, and in generator and portable panel supplies. Switches and Sockets Selection Guide — Selection guide for flush and surface wall switches, grounded and weatherproof sockets, modular mechanisms and frames, power strips and dimmers. Panels and Equipment Selection Guide — Complete selection guide for electrical enclosures, combination boxes, junction boxes, DIN rails, busbar distribution blocks and panel thermal management equipment. What Is a Grounded Socket? Grounded Wall Socket Selection Guide — A grounded socket is a wall socket with a ground contact in addition to two current-carrying slots; this guide covers series, cover, IP44 and child protection. Sleeves Selection Guide — Sleeves are divided into heat-shrink, fiberglass, silicone-coated fiberglass and ready-made sets; the type is mostly decided by the operating temperature. Cable Trunking Selection Guide — Cable trunking is divided into in-panel, plastic, adhesive, floor and sheet metal types; selection is made by place of use and by matching bends and joiners from the same series. Terminal Blocks Selection Guide — A terminal block connects conductors to each other or to a device by screw, spring or clamping connection. DIN rail, spring-connection and fused types. Panels Selection Guide — Panels are divided into metal sheet, plastic, MCB and construction site types by housing material and internal layout; environment and IP rating are evaluated first in selection. Blind Plugs Selection Guide — A blind plug closes a gland hole; polyamide and nickel-plated brass types exist, and the plug must match the hole's thread system (metric, PG) and size. Spiral Conduits Selection Guide — Spiral conduits split into plastic (polyamide, polypropylene) and metal groups; material, temperature range and slit or closed construction drive the choice. Dimmers Selection Guide — In a dimmer, R indicates resistive, L inductive and C capacitive load; choose by lamp or transformer type and whether the lamp is dimmable.
