What are IP Ratings ? [RESOLVED]

The IP Code, or Ingress Protection Code is a standard which classifies and rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water. It is published by the International Electrotechnical Commission. The equivalent European standard is EN 60529.

For example a typical Wiska IP66 junction box like this https://amzn.to/3x5nAzP will provide complete protection against dust and powerful waterjets or heavy seas.

The chart below shows what each number means.

How to spot the fake IET books

According to the IET website they are aware of several counterfeit versions of its books in circulation.

BS 7671, the On-Site Guide, Guidance Note 3 and the Code of Practice for In-Service Inspection and Testing of Electrical Equipment are all known to have counterfeit versions in circulation, with varying numbers of mistakes in each.

Adhering to text in counterfeit electrical books can lead to non-compliant installations, which could be potentially very dangerous. BS 7671 exists to ensure that electrical installations are safe and to reduce the risk of fire or electric shock. Using corrupted information undermines the safety of your work.

To help combat this issue, current and future copies of BS 7671, the On-Site Guide and Guidance Note 3 all contain a hologram. This currently contains the IET logo in two sizes and the word ‘GENUINE’ as well as a number of additional features.

Although this can help you to identify a fake, it is not foolproof, as counterfeiters can produce similar versions of the hologram. The only way to be certain of buying a genuine copy of our books is to buy directly from the IET, or from one of the approved suppliers (Amazon been one example)

The IET is a charity, and the dissemination of information is part of our charitable remit. Any surplus from the sale of the books is re-invested into producing guidance for industry, through our publications programme and Wiring Matters magazine. The proceeds from the sale of fake books do not support the industry in any way and harm the IET’s ability to fulfil its remit.

If you think you might have mistakenly purchased a fake copy of an IET book, please get in touch with the IET with as much information as possible about the book and where you bought it.

Unfortunately, the IET cannot reimburse purchases bought from suppliers of counterfeit books, nor assist with the resolution of disputes, but they are working to shut down any counterfeiters that they find and take legal action against them to reduce the risk to the industry.

What are the main changes in the latest Part P 2013 edition of the Building Regulations?

There are two main changes in the latest version of Part P of the Building Regulations. The first change relates to the range of electrical installation work which requires notification. The range has been reduced, previously work in kitchens and outdoors was notifiable. Under the new regulations, unless the work requires the provision of a new circuit and is not in a special location it will not require notification.

The other major change is regarding the use of a registered third party to certify notifiable work. In the previous edition of the Building Regulations, an electrical contractor carrying out work covered by Part P but not registered with a competent persons scheme was required to notify Local Authority Building Control (LABC). It would then be down to LABC to consider if the proposed works were acceptable under Building Regulations. Under the current edition of Part P, any installers which are not registered with a competent person scheme, are required to get work signed off by a registered third-party.

Part P – What types of electrical work are notifiable?

The introduction of the latest version of Part P was introduced on 6 April 2013, the range of works requiring notification has been reduced.

Notifiable works

  • The installation of a new circuit
  • The replacement of a consumer unit
  • Any addition or alteration to an existing circuit in a special location

Non- notifiable works

  • All other work is considered non-notifiable, namely additions and alterations to existing installations outside special locations, maintenance, replacement and repair work.

Special locations and installations

  • A room containing a bathtub or shower
  • A room containing a swimming pool or sauna heater.

A special location means:

  • A room containing a bath or shower, the space surrounding a bath tap or showerhead where the space extends vertically from the finished floor level to a height of 2.25 metres or the position of the showerhead where it is attached to a wall or ceiling at a height higher than 2.25 metres from that level or horizontally where there is a bathtub or shower tray, from the edge of the bath tub or shower tray to a distance of 0.6 metres. Or where there is no bath tub or shower tray from the centre point of the shower head where it is attached to the wall or ceiling to a distance of 1.2 metres.

Halogen lightbulb sales to be banned in UK under new government plans

The government has announced plans to end the sale of halogen light bulbs from this September, as part of the UK’s wider efforts to tackle climate change.

Legislation being brought forward this month will also include the removal of fluorescent lights from shelves from September 2023.

Currently, around 2 thirds of bulbs sold in Britain are LED lights, making a considerable impact in improving the energy efficiency of the country’s buildings. They last 5 times longer than traditional halogen lightbulbs and produce the same amount of light – but use up to 80% less power.

The UK began phasing out the sale of higher-energy halogen lightbulbs in 2018. The new legislation would mean retailers will no longer be able to sell the majority of halogen bulbs for general household use in the UK from 1 September.

To help people make the switch, ministers are also announcing that all light bulbs will start to feature new energy efficiency advice via ‘rescaled’ energy labels on their boxes. The labels will simplify the way energy efficiency is displayed on a new scale from A-G, doing away with the A+, A++ or A+++ ratings. The new labels will raise the bar for each class, meaning very few bulbs will now be classified as A, helping consumers choose the most environmentally friendly bulbs.

This measure is expected to mean that LED light bulbs will account for 85% of all bulbs sold by 2030.

In addition, the government also plans to start phasing out the sale of high-energy fluorescent lightbulbs, with a view to bringing an end to their sale from September 2023.

Taken together, these new rules will mark a significant shift to more energy efficient and longer lasting LEDs and will stop 1.26 million tonnes of carbon being emitted every year – the equivalent of removing over half a million cars from the UK’s roads.

The move is part of a package of energy efficiency improvements to electrical appliances, which will save consumers an average of £75 a year on energy bills.

Energy Minister, Anne-Marie Trevelyan, said:

We’re phasing out old inefficient halogen bulbs for good, so we can move more quickly to longer lasting LED bulbs, meaning less waste and a brighter and cleaner future for the UK.

By helping ensure electrical appliances use less energy but perform just as well, we’re saving households money on their bills and helping tackle climate change.

Today’s plans also include a ban from September on the sale of lighting fixtures with fixed bulbs that can’t be replaced – meaning the fixtures have to be thrown away. Fixtures such as these account for 100,000 tonnes of electrical waste every year – out of a total 1.5 million tonnes of electrical waste each year.

Minister for Climate Change, Lord Martin Callanan, said:

Flicking the off-switch on energy inefficient light bulbs is a simple way that households can save money at the same time as saving the planet.

Phasing out halogen bulbs in favour of LED alternatives that last longer, are just as bright and cheaper to run, is another way that we are helping tackle climate change.

Chief Executive of Signify UK, which owns Philips lighting, Stephen Rouatt, said:

We welcome the UK government’s next step in the transition towards more sustainable lighting products. Using energy-efficient LED equivalents for halogen and fluorescent lighting on an even broader scale will significantly help the UK on its journey to decarbonisation, as well as lowering the annual electricity bills for consumers.

Overall, the government’s package of energy efficiency improvements will also cut 8 million tonnes of carbon emissions in 2021 by reducing the amount of energy products consume over their life-time – the equivalent of removing all emissions from Birmingham and Leeds each year.
