2 x 5-Way DP 100A Service Connector Block 35mm² is rated 4.0 out of 5 by 8.
Rated 5 out of 5 by from Good block feels brittle Excellent block, used for supplying 2 consumer units with 25mm tails- note that screws need to be backed right out to accomodate 25mm tails ( i removed screws completely to ensure i could see that the copper was fully seated in both screw holes then re-inserted screws very tight as I was paranoid they would drop out.) Had no issues

Rated 3 out of 5 by from brittle cover Solid connection blocks and does the job OK but the lid is brittle and was already broken on my purchase

Rated 4 out of 5 by from great for adding second board heavy duty brass blocks, drill out holes with a 10mm hss bit, hole for seal, nice tidy box for a pro job

Rated 3 out of 5 by from Careful - they're fragile Holes drill out easily enough, but it would be nice to have some markings indicating how much to strip back the cable. Don't try to force anything - the material is very brittle and cracks easily.

Rated 5 out of 5 by from just the job needed to link two consumer units this was just the job for what i wanted to do
Date published: 2014-06-18
Rated 4 out of 5 by from Fast easy install After struggling with the existing one on a job I installed this instead found it easy to fix knock outs are hard but 10mm drill bit on it takes it out clean it fits 25mm tails comfortably with other sheath. The previous comment said the entry holes were only 9mm mine were at least 10mm was probably talking about the 25mm not this 35mm one.

Rated 3 out of 5 by from Has issues with cover and base GOOD Nice chunky TB and slotted screws Cable entry holes are 10.7mm so should take 25mm² outer sheath OK if fully opened out (see below) THINGS TO NOTE Terminal block holes are 9mm but the screws have the first part of the thread plain so the full diameter can’t be used Fixing holes are flat-bottomed for pan-head screws POOR Base of the one I bought was distorted and proud at the centre so needed filing to sit flat Cable entry knockouts don’t punch out cleanly and need filing Fixing screw holes need to be drilled out No marking or instruction to say to Live goes at bottom, Neutral at top No marking or instruction giving the cable stripping lengths BAD Cover doesn’t sit properly due to what seems to be a tooling modification to enable the use of a seal on the screw. It’s more than possible that over-tightening the screw would crack the cover. A few minutes work with a Dremel-alike sorted it but I’m not entirely happy with the fit of the cover WOULD I BUY AGAIN? I’d look at the competition next time unless the cover issue is sorted (Review based on Greenbrook CB6 Batch 4513 bought Guildford 5/6/14)
