Choosing a socket combination: AMAXX vs EverGUM vs DELTA-BOX

Customers call it a power box, distribution box or portable power box; we call it a socket combination. Five things decide the model: number and rating of outlets, incoming current, Type A RCD, IP rating and whether it is pre-wired.

Naming first: what customers call a power box / distribution box / portable power box is what we and the manufacturer call a socket combination — several industrial sockets (sometimes with switches, RCDs and MCBs) integrated in one enclosure, fed by a single incoming cable to supply several circuits.

Five things decide the model

DecideHow
(1) Outlets and ratingsHow many circuits? Each 16A / 32A / 63A, and how many poles (neutral needed? see counting poles). Example: 1420 is "2×16A + 1×32A, IP44".
(2) Incoming currentSum the circuits and add headroom; common ratings are 25A / 40A / 63A / 100A
(3) Earth leakage protectionSites, damp areas and temporary power should have a Type A RCD; 25 of our models include one
(4) IP ratingIP44 is enough indoors and dry; outdoors, wash-down and yards need IP67. The enclosure material also affects weather resistance (below)
(5) Pre-wired or notModels marked "pre-wired, ready to install" save on-site wiring time

The three series, as they differ in our stock

SeriesEnclosure and featuresBest forIn stock
AMAXX®Modular plastic enclosure; some in AMAPLAST or AMELAN® (chemical resistant); expandable in sections (with 15696 a lightweight frame carries 2/3/4 sections); some with Type A RCDFixed installation in workshops, production lines, plant rooms38
EverGUMPermanent rubber enclosure (RAL1003 signal yellow), impact and weather resistant; many with Type A RCD; 16A–100ASites, temporary power, outdoors — anywhere it gets knocked about8
DELTA-BOXCable clamp, internal strain relief, suspension hook; AMAPLAST enclosure and insert; pre-wiredPortable / suspended work areas4
Other combinationsPurpose-built enclosures, including the reefer combination 940027 (CEE + DUO interlock + SCHUKO + 3× MCB 32A)Special applications24

One further reefer combination is classed separately; see choosing reefer container sockets.

Two questions we get a lot

What is a Type A RCD? — Besides AC residual current it also detects pulsating DC residual current, so it is more reliable than a plain Type AC device on circuits with VFDs, electronic ballasts or chargers. For sites, workshops and anything with a variable-speed drive, specify Type A.

What does "pre-wired, ready to install" mean? — The sockets, protective devices and busbars are already wired and checked inside the enclosure; on site you connect the incoming cable and fix the box. Ideal when the schedule is tight or you do not want a second wiring stage on site.

Combination unit or individual sockets?

  • Two or more circuits plus protection → a combination unit is simpler: one enclosure, one feed, protection included, and it looks neater.
  • A single circuit in scattered positions → individual wall-mounted or add-on sockets are more economical (see the mounting names).
  • It has to move → EverGUM (rubber, impact resistant) or DELTA-BOX (hooked, portable).
Not sure how many circuits or whether you need an RCD? Send us (1) what equipment it will feed and their power (2) three-phase or single-phase (3) indoors or outdoors/site, and we return a configuration — circuits, ratings, incoming current, Type A RCD or not — with product photos and datasheets.

How to choose industrial plugs and sockets: 5 steps to the right model
Current, poles, IP rating, mounting and brand — follow these five steps and you pick the right industrial plug or socket the first time, without trial and error.
IP44 vs IP67: what the two numbers really mean
The difference is not just a bit more water resistance. What IEC 60529 actually specifies, and how to choose for outdoor and wet areas.
Reading MENNEKES model numbers: 32xx / 27xxx / 13xA
How MENNEKES numbers its industrial plugs, sockets and connectors, and how to recognise a model at a glance.
Reading the MENNEKES 93xx series: 9322 / 9342 / 9372 / 9382 compared
93xx is the MENNEKES wall-mounted IP67 industrial socket series. The last digit gives the voltage, the third digit the poles and current. The full 9300–9382 table and the four comparisons people ask about most.
Can MENNEKES sockets be interchanged with other CEE brands? Check the clock position first
Interchangeability is not about the brand but four things: current, poles, clock position and IP rating. With the clock positions we verified against our own stock (110V = 4h, 230V single-phase = 6h, 400V 3-pole = 9h, 400V 4/5-pole = 6h, 500V = 7h).
Counting poles on industrial plugs and sockets: 3P / 4P / 5P explained
One model is written 3P on one page and "3-pole" on another — it is the same number, and the earth is always counted. With a table checked against the manufacturer datasheets (voltage and clock position included).
What people call industrial sockets: add-on = panel-mounted = flush-mounted
The same product has several names: add-on socket, panel-mounted socket and flush-mounted socket are the same thing, while wall-mounted is a different one. A full glossary so you quote the right model.
16A / 32A / 63A / 125A: how to pick the rating in three steps
The rating follows the equipment current with at least 20% headroom: 16A ≈ 7.5kW, 32A ≈ 15kW, 63A ≈ 30kW, 125A ≈ 60kW (three-phase 380V). With the conversion formulas and the four commonest mistakes.
