Hi Mike, I think we have a terminology problem. Most Electricians working on single phase would call a particular device 2-pole, when in fact it is 1-pole + N. The mcb senses overcurrent or fault current and trips the circuit. The neutral switch contacts open to achieve isolation only. These...

Hi Mike, I no longer own SBS Trade Sales, but the single module CRB rcbos are definitely independent 3mm 2 pole switching. Checkout the terminal configuration, two in, two out .And no flying leads. Some others achieve genuine 2 pole by internally switching a neutral flying lead..

An apprentice electrician shows up for work, over an hour after he was supposed to. His boss asks Wire you insulate?

For those members involved in EV Charging Stations and those considering Double-Decker DBs, the attachment may be of interest to you.

OOPS!!!, Sorry about that, Deke. Nick is a regular customer, so I must have had a senior moment. The Price List is on my website,   www.sbstradesales.co.uk , or if you email me on [email protected]. I will send you a copy. Email is better for me, as I don't visit the Forum on a...

Hi Nick, This is another view of the assembly, showing the 2 x busbars

Oops!! Should have put some words in. Option 1  -  Fit a new Board with Compact RCBOs, eliminating  "God knows" how many neutral / earth flying leads, as well as creating far more room for circuit conductors. Option 2  -  Remove everything from the DIN rail of the existing box and fit a...

Hi Rob, I checked my stock and the numbers and the labels are as per the first photo, as I suspected. I do offer L/H Main Switch, but the neutral terminal bar still stays at top right. The earth terminal bar can't move, because it provides earth to the box via a bolt. You don't need the neutral...

Hi Rob, I'm glad you noticed it, because I hadn't!!! The first photo has the redesigned box and the second is the older version. I think that probably explains it, but I will check my stock tomorrow.

Here's one without numbers, Andy!!

Hi Sharpend, you mean something like this? Without flying leads, it gives you room to make a really neat job. With regard to the ECD RCBOs, they used to do only the range like the one at the end. I sold it, as did MK, Chint, TDline, Contactum, LiVE and a few others. It is a generic JVL-63...

Hi Tamrat 8 years ago, I attended a funeral in Gerji and was shocked at the standard of domestic wiring there. So much so,  I offered Addis University a free course on Domestic Wiring for existing and new electricians. I set up the course with the Uni's Head of Electrical Engineering and got...

PLEASE NOTE, I WILL BE IN CHINA  17th October until 3rd November 2017 All my Customers have been notified by e-mail, but for those who didn't read the message and for other potential customers, this is a reminder that I will not be available during this period. Since virtually all my DBs are...

Hi Marvo, Yes I do stock a limited range and qty of my Compacts in C curve, although I rarely get asked for them. I've got some 6A, 16A and 32A and I have just shipped 48 x C20s to Tanzania. They are certified to IEC 61009-1 and are CE certified. They are a true 2-pole device and can be fed...

The red was my idea, but it turns out my son didn't like it either. In fact, nobody did. You will be pleased to learn that we will ditch the red and come up with a proper site, as Lurch suggested. If anybody has useful input for me, I would be happy to consider it. It won't happen overnight, so...

Hi SUD, A good way to solve your problem is to use the IET Estimation Method, using the formula   Pmax = gxP1, where Pmax  is the estimated maximum demand on an installation, P1 is the actual total installed load, usually on the basis of continuous duty and g is the diversity or de-rating...

You could say the loud colour has certainly attracted attention, which was the object of the exercise. However, I am open to suggestions. It didn't go down too well with my wife's family in Stockport, who are all Man City fans, but I did use to be a Sheffield United fan donkey's years ago, when...
