Terminal block vs lever connector

Updated: October 2026

You can reach the joint, and you are choosing a screw choc strip or a lever splice for that one connection. A terminal block vs lever connector decision in this set is not a decision about a WAGO 221. The levers here are ZFYQ at about £5.99 and flintronic at about £7.98. Use the screw strip when you can reopen the fitting and the current cell matches. Use a lever when the rose is tight and a printed range covers the wire. Neither is a joint you bury. The full table is the [terminal block comparison](/hub/diy-supplies/terminal-block). Peter F. checked the listings on 16 October 2026. Links to amazon.co.uk are affiliate links.

They are not the same product

A screw strip is a row of brass tunnels you cut and tighten. In this set that is GTSE, Blackspur, both SDFIXINGS listings, LTMMC, Brackit, Funver and XINXINGDINGSHENG. A lever is a spring you open with a tab. ZFYQ’s connector cell says Quick Connect. flintronic’s connector cell says Push-In. Neither cell says WAGO. The UK search still answers lever with a WAGO 221. Retail pages quote 32 A and 450 V for many 221 connectors, and a range such as 0.2–4 mm². Those figures are not in the ZFYQ or flintronic cells. Conductor, circuit and enclosure decide. Brackit and XINXINGDINGSHENG say tool-free in a bullet and tighten the screws as well. The connector cell on both is Screw. That clash does not turn a choc strip into a lever.

Choose the screw strip when you can get back to it

If you can still get a screwdriver in, a screw strip is a joint you can remake later. Professional Electrician’s piece on what accessible means in BS 7671 describes that duty for a screw junction box. You are not pasting the article onto these listings. Match a current cell, not a shared bullet. GTSE at about £7.99 names two 3 A and two 15 A strips, while the cell says 15 A and the voltage cell says 400 V. The SDFIXINGS cells say 3 A or 5 A, against shared bullets that run to 60 A. Blackspur at about £3.60 has the same mix and UK texts in which screws strip and housings crack. Skip the screw strip when the rose is too tight, or when the only pack is XINXINGDINGSHENG at about £3.19, whose UK reviews describe split brass. Cutting and tugging sit on the how to use a terminal block page.

Choose the lever when the rose is tight and the range is printed

ZFYQ is 35 pieces at about £5.99, with a 250 V cell and no current cell. The bullet states solid and stranded 0.08–2.5 mm² and flexible 0.08–4 mm². Six UK texts in a file of 220 at 4.6 mention ceiling lights and a ceiling fan, and they do not state a fault. That is the lever when the rose is cramped and the wire sits in that range. Do not invent a 32 A rating because another brand prints one. flintronic is about £7.98, with 4.6 from 6,474 reviews. The title says 34 pieces and the unit count says 50. The conductor figures disagree, and UK texts say some levers snap unless you tug the wire. The larger file does not make flintronic the winner.

Neither replaces the box

A maintenance-free setup, on that same Professional Electrician page, is screwless terminals plus an enclosure, marked to BS 5733 with an MF mark. The connector alone is not that accessory. ZFYQ is not maintenance-free because the bullet says it locks without tools. A screw strip is the accessible kind of joint, not the buried one. No capture prints an IP rating. If you can reopen the fitting and match a current cell, use a screw strip. If you cannot get a screwdriver in, and the wire sits in ZFYQ’s range, use ZFYQ, and use flintronic only with a tug on every wire. If the joint would be hidden, buy neither. The terminal block buying guide is the order of those checks, and the terminal block for lighting page is the England line for an existing light.

Common questions

When is a screw strip the better choice?
When you can reopen the fitting and the current cell matches the job. GTSE’s package line names two 3 A and two 15 A strips, and the current cell still says 15 A only. The SDFIXINGS cells say 3 A or 5 A, which is the figure to use rather than the shared 60 A bullet. Skip a screw strip if the reviews describe split brass, or if the rose is too tight for a screwdriver.
When is a lever splice the better choice?
When the space is tight and the printed conductor range covers the wire. ZFYQ states 0.08–2.5 mm² for solid or stranded and 0.08–4 mm² for flexible, at 250 V, with no current cell. UK texts in the sample mention ceiling lights and a ceiling fan. flintronic is the alternative only if you tug every wire, because its reviews include levers that snap.
Are the lever packs in this set the same as a WAGO 221?
No. Search results describe a WAGO 221, often with 32 A and 450 V on retail pages. ZFYQ and flintronic do not print those figures. flintronic’s 32 A number appears in a review, not in the listing. ZFYQ’s voltage cell says 250 V and it has no current cell. Treat WAGO’s page as the product the search returned, not as a rating for these two listings.
Can you bury either joint?
No. Screw terminals are the accessible kind of joint, not the buried one. A maintenance-free arrangement described for BS 7671 is screwless terminals and an enclosure together, with an MF mark. These listings do not show that mark. No capture prints an IP rating. Tape is not an enclosure. If the joint would be hidden, choose neither pack.
Does a higher review count make flintronic the winner?
No. flintronic’s 4.6 from 6,474 reviews is the largest file here, and it is also the file in which levers snap and wires pull out unless tugged. ZFYQ is 4.6 from 220 reviews, with a conductor range the page agrees on, and only six UK texts in the first 50. Volume is not a current rating. Pick the lever whose printing matches the wire, then tug it.
