A dimmer, even a Varilight which are really good, have a minimum load current at which they can operate. It's never been a problem in the past with incandescent lamps because the wattage is so high it ensures adequate current flow once you get a couple of lamps on the circuit. It's not always...

You also need to beware of the minimum load, believe it or not.

A consumer unit is not required to be able to “contain a fire”, the IP rating requirements have not changed for many editions, & “contain a fire” is not the term used. The clause in BS 7671 is 421.1.201. Screenshot attached, I get the IET books electronically for the work I do with them.

The issue with plastic enclosures is compliance with the wiring regs. Almost none comply. So unless the workshop is sufficiently detached from the main dwelling then it is doubtful that a plastic CU enclosure can be used. DIY or not, the insurance company may have a view of the requirements for...

Breach of the terms of the policy is also grounds to refuse a claim is it not.

If you are in breach of said contract I don’t think that they have to pay out. That’s certainly the case for business policies.

If “electricians” on the Screwfix forum are making recommendations on mixing and matching circuit protection devices and boards then it’s not a good place to get advice. For over 30 years the practice of “mixing and matching” boards and protective devices has been against the product safety...

Of what I am able to read (on my phone) those observations are not a C1 unless the cable shows evidence of thermal damage, in which case it would have to be replaced. A lack of coordination would “normally” only attract a C2. I would love to see the BS7671 clause for the lack of ducting on the...

In over 30 years of working on machinery of all kinds including wood working machinery, I have never seen a thrust race that is sealed or shielded. By design it’s not possible to do that.

Almost certainly neither if it’s a thrust bearing.

Post a copy of the EICR suitability redacted for privacy? There are very few things that merit a genuine C1 code. Mainly exposed live parts. If the loop impedance is too high for the fuse to disconnect then that a C2. Scheme rules are such that a C1 cannot be ignored the inspector is compelled...

It also must comply with the Supply of Machinery Safety Regulations/Machinery Directive. That’s the law. Unless it’s CE/UKCA marked it cannot legitimately pass a LOLER inspection.

They aren't good in a dirty environment, but, then again we used to use the same waylube oil for the ballscrews and the slides, and the system was unfiltered, and re-circulating. Some areas were total loss, others weren't, which might be a better description. You might have a problem with...

Grease + grinding swarf = lapping paste! I’ve seen it too many times. The accuracy of the positioning is going to be dependent on the accuracy of the leadscrew. Can you investigate a ballscrew? As far as scraping the slides go, it’s possible, but not easy, and yes I have done it, and yes it was...

The NVR on a motor driven piece of equipment is a safety device. It’s required by the product standards used for compliance with safety law.

How did I do on the instructions?

The requirements for insp and testing are within the British Standard, this document is referenced in the Approved Document (P) for compliance with the Building Regulations. The onus is on the person undertaking the work to inspect and test, complying with the requirements of BS 7671. The onus...

For information, as the job is completed by the sound of things. “Chock block” connectors “stuffed” in the ceiling void, is not compliant with BS7671. I understand that you are doing this as a DIY job, but, you need to realise that your insurance company will have expectations within the small...

I fully agree that it is wrong. The trouble is that you are trying to take on a broken industry. Not enough people within the electrical industry (BS7671 side) want changes, and there are not enough competent operatives in the industry to pick up the pieces. Hence why you are on a hiding to...
