The unidirectional device has the word 'out'. There are no markings on a bidirectional device.

BEAMA published a tech update last year and there was an article in wiring matters 99. The term is unidirectional, not omni. The amendment was announced a short while back. Hi-directional means the device works in both directions so is suitable for prosumer units. Unidirectional devices have an...

I would go back to the start of the thread, as it has meandered. 522.6.202 refers to 3 terms which create the zones. The terms are defined in Part 2 as follows: 1. Point - A termination of the fixed wiring intended for the connection of current-using equipment. 2. Accessory - A device...

Building regs do not apply in a workplace, so part p is irrelevant. The regs which DO apply are EAWR and RIDDOR and an installation where a person receives a shock will be of interest to HSE. There are definitely legal and illegal electrical installations.

How long was the inspector on site?

Hope 2024 brings health and happiness to all.

Hope everybody has a Merry Christmas and a Happy New Year.

I don't get this. For sockets we have given designs. The formula for the tabulated current carrying capacity is It = In / ( Ca Cg Ci Cf )

The cable is sized on the MCB rating, not the load.

Incredible. So you have no interest in any definitions, so a circuit is just an OCPD and a piece of cable.

I meant installing the water heater, by a pro (and by implication a conscientious diyer) would result in an eic for a new circuit. For a shower, I would describe an OCPD plus cable (with no shower connected) as a partial circuit. This would apply for any other fixed wired item. The cooker and...

In BS7671 a final circuit is defined as - 'A circuit connected directly to current-using equipment, or to a socket-outlet r socket-outlets or other outlet points for the connection of such equipment.' Does this answer your question?

If there is no shower in the bathroom, it woold be a stretch to say there is a circuit. If this was a pro installation, there would be an EIC. Surely this is a new circuit.

That's out of date and as far as I recall, was the BS7671 definition for a 'competent person' up to the 17th edition amendment 3 (but I haven't checked). In the current edition, there are 3 sets of people. Skilled Person (electrically) - Person who possesses, as appropriate to the nature of...

Completely irrelevant. Irrelevant. This is a quote for the job and the prices are high, given the parts are freely available at much lower cost. Do you ever read the actual question? Sunray has stated the company is supplying and fitting.

That's a steep estimate for a shed CU with 4 circuits and you still haven't said why the current fuse box has a C1 code. As already pointed out, the shed doesn't necessarily need a CU. In your first post you said there were 2 5amp fuses and 2 16amp breakers, but the quote has a 32amp rcbo. If...

@SUNRAY What did you find when you went to the site? What reg(s) did the EICR refer to when the inspector coded C1?
