Electrical Supplies
On this Electrical Supplies category page, the range runs from everyday white plastic switches and 13A sockets through to more specialist items like metal adaptable boxes, RCD add-ons, and conduit bends for garage or workshop installs. Some partners group variants under one tile, while others split each colour, gang count, or IP rating into separate entries, so the same back box can appear more than once with different depth or finish. It’s a practical mix. Expect movement over time as partners rotate lines, update packs (single vs 10-pack), or swap a listing from “with screws” to “screwless” without changing the product family. A few items are purely maintenance-led, like replacement faceplates or blanking plates, and they sit alongside install hardware such as glands, grommets, and trunking couplers.
Read on for how Electrical Supplies listings are grouped, how specs are shown, and what varies between partners
Core groupings you’ll notice first
Most ranges cluster around sockets and switches (1–4 gang, 13A, 10A fan isolators), protective devices like MCBs and RCDs, and enclosure items such as adaptable boxes and pattress boxes. Some partners publish a single tile with colour options (white, brushed steel, black nickel), while others split each finish and gang count into separate entries. That duplication is normal. With Screwfix, you’ll also see trade packs beside singles, so a 25mm back box might sit next to the same depth in a 10-pack with different fixings. For electrical wiring accessories, check faceplate size (86mm vs larger plates) and whether terminals are screw, clamp, or quick-connect.
Formats, packs, and how variants get published
Electrical Supplies frequently appear as singles, multipacks (5, 10, 50), or mixed bundles where clips, screws, and wall plugs ship together. Small hardware changes the listing shape. Toolstation entries sometimes separate “box only” from “box + lid” for adaptable enclosures, while other partners roll lids, gaskets, and fixings into one SKU and show fewer variants. For cable management supplies, watch pack counts on mini trunking (2m lengths) and whether corners, tees, and couplers are separate lines or included as a starter set. It gets messy fast—especially when the same trunking width is offered in two finishes.
Sizing and spec fields that differ by retailer
Specs are not always shown in the same place, even when the item is identical. One partner leads with diameter and thread (20mm vs 25mm, M20 vs M25), another leads with box depth (25mm, 35mm, 47mm) or module count for DIN rail enclosures. Small numbers matter. For electrical conduit fittings, confirm bend angle (90° vs swept), conduit type (rigid vs flexible), and whether the fitting is solvent-weld, compression, or push-fit, because those details can be split across the title and the spec panel. A “20mm” entry can still differ by internal bore or locking ring style.
Materials, build details, and functional features
Material is a real separator: PVC trunking vs galvanised steel conduit, ABS adaptable boxes vs die-cast metal, and faceplates in plastic, stainless steel, or a coated finish. It’s not cosmetic only. Electrical2Go listings for enclosures and accessories often specify IP ratings (IP44, IP65) and gasket presence, which changes suitability for sheds or outdoor walls, while other partners emphasise knockouts (20mm/25mm) and lid screw type (captive vs standard). For consumer unit accessories, look for busbar compatibility, blanking plate width, and whether the part is designed for a specific board layout rather than being universal.
Common checks people make before choosing
Match the electrical rating and the physical format first: 13A vs 5A, 1-gang vs 2-gang, and whether the plate is screwless or screw-fixed. Then check enclosure and entry details like knockout count, gland size (M20/M25), and whether a junction box is 3-terminal or 5-terminal. Labels vary. For electrical junction boxes, confirm box size (for example 32A-rated larger housings vs compact maintenance boxes), terminal material (brass vs plated), and whether the lid is captive-screw or clip-on—small build differences affect access during fault-finding. Some listings carry two similar photos; the depth figure is the tie-breaker.
How discount codes can reduce the cost of Electrical Supplies shopping with Discount Promo Codes
Discount codes relate to reduced cost when buying Electrical Supplies items such as 10-pack fixings, 2m trunking lengths, or a 25mm conduit bend, where the listing is tied to a specific retailer’s checkout rules. Not every retailer publishes codes at the same time. Discount Promo Codes provides access to discount codes for partner retailers, and links to a retailer’s discount code page may sit alongside product listings rather than inside the product detail itself—placement varies by merchant. Direct Trade Supplies is one example of a partner retailer that may appear in this category view. For electrical cable clips, the product context still matters (6mm vs 10mm, round vs flat, white vs black), because codes apply at retailer level, not to a single variant. Separately, the platform supports a monthly charity donation, with 20% of profits donated.
