Friday Boiler Course

Attended a course on steam boilers that did not really cover much more that we knew already.

The sight glass proving method as altered though. For those not in the know, sight glasses are situated on the side of the boiler and tell you how much water is in the boiler. Too little and the boiler can be potentially a bomb just getting ready to explode.

There are three handles or taps on the sight glasses which should all be facing downhill, this gives a quick visual indication that they are set correctly for normal operation. The top is the steam valve, middle is the water valve, and finally the bottom is the drain valve.

New gauge glass procedure is now

steam valve - closed- horizontal
water valve - closed- horizontal
drain valve - open - horizontal

gauge should empty and after initial blast should stop indicating that steam and water valves are holding

Opening and then closing the steam valve will wash the steam line and you shoulkd see shimmers as steam passes through.

Opening and closing the water valve will wash the water line and you should the level rise in the sight/gauge glass.

Close the drain cock, slowly open the water cock, sight glass should fill up, slowly open the steam cock and the water level should slowly drop to match the actual boiler level.

Have a look at the Spirax Sarco website for more on steam boilers

2391 Theory passed

Just thought I would let you all know I have passed the theory side of C&G 2391 Inspection and testing. It is now down to the practical and then yet another qualification.
Going on a defribrulator course on Monday so will let you know how that goes.
Been adding some more content to http://www.pullthegirls.co.uk in respect of online dating.
Going to try and get some Autumn photographs too, these will show the colours of Autumn leaves.

An end of Split Consumer Boards??

The draft addition of the 17th Edition, BS7671:2008 contains new requirements for bathrooms. All circuits will need to be protected by 30mA RCD so this would mean the lights.

If you look at the logic, what would be the point in having a split consumer unit just for lighting circuits that are not supplying bathrooms or outside lighting?

Welcome any comments on this

Monday, Interview

Went for an interview for a tutoring post with respect to the 17th Edition or BS7671:2008. Everyone that knows me thought I would have no difficulty in obtaining the post. I had been on nights and with traffic and getting into the place made me late. Not a good start to the interview, being tired did not help with coming up with suitable answers to the questions either.

On Wednesday I had a feeling that all had not gone well and sure enough I got a phone call saying that I had not been successful. Still even though I cannot tutor people and get paid for it. I can still try and help on here by offering advice on the 17th Edition.

17th Edition Wiring Regulations

In 2008 the 17th Edition of the wiring regulations that are now called BS7671 will come into force.

The final copy is not available yet, but a draft was made avaialble for public comment. Let us look at some alterations between the draft and the present 16th Edition

In the draft it appears that the layout of the regulations follows the International Electrotechnical Commission’s (IEC) numbering system, this means that Part 6 and Part 7 are reversed.

Part 1 additions are protection against voltage disturbances and protection against electromagnetic influences

Part 2 includes some new and changed definitions

Part 4 includes several significantly changes, remember direct contact and indirect contact, these are now basic protection and fault protection respectively. A lot of jiggling with this part as taken place. Supplementry protection with the use of RCD comes under the heading of additional protection.

With the normalised voltage for the UK having changed to 230Volts the earth fault impedances shown in the tables are different.

More to come later
