Loosing 17KW

So by merely saying that there is nothing wrong with improving safety standards I am "doom mongering", and you tell me to get a grip 8-).

Greg

I don't know how you got onto air travel, except to give you a lead into taking another poke at me, but do you really think that aircraft shouldn't need to be inspected for 30 years as seems to be the feeling here about houses?.

Greg

Greg,

There is a distinct echo of a previous contributor coming through loudly here! You don't by any chance live in Chippenham and have an interest in Amateur Radio by any chance?

Wrong I'm afraid, part P of the building regs specifically covers any building on or in the land associated with any domestic premises, the ONLY exclusion is business premises to which the factories act applies and lifts in communal dwellings which have their own regs.

Greg

A choice between your family's safety and booze, yep, that's a real tough one...

Greg

So much negativity and you still don't grasp the concept that safe practices are paramount. Just because you Polo has "all" the safety features imaginable, isn't going to save you if you drive like a prat and attempt to intimidate a 44 tonne juggernaut.

As for my house, it may cost as much as a airliner to run, but it is still just a static ground based unit. The airframe check and routine maintenance will resume after breakfast. Scaffolding is in place to facilitate any remedial work required in the porthole areas, prior to a full airframe repaint.

A good question, and one I will answer regardless of those who think they own this group and try to stifle free discussion:

It goes like this, inverters produce a lot of electrical noise so have filters on the mains input to minimise the disturbance they cause, unfortunately such filters cause earth leakage current because they have capacitors from the phase and neutral to earth. In extreme cases this earth leakage current can trip a 30mA RCD that is required on socket outlets and the proper answer is to wire the inverter in directly rather than plug it in. In fact the installation instruction for an inverter that produces too much leakage current should instruct you to wire it in.

Even if one inverter has a low enough leakage current to plug in, the leakages of all the devices plugged into the circuit add up and can trip the RCD, a common problem with offices and IT suites because PCs have a similar problem, as do many modern electronic power supplies.

I hope this helps.

Greg

My god you really can twist things can't you, I'm the one supporting making things safer for people, supporting new regulations that are intended to reduce the number of cowboy electricians out there that are conning people and risking their lives, how effective they will be is hotly debated but they are at least an attempt to improve things. If you want to see something negative try reading your own posts...

I'm afraid it's you who doesn't grasp the concept that the average member of the public hasn't a clue when it comes to safe electrical practices, so needs protecting with safety devices. Or should we not have shutters on 13A sockets for example?, or shielded pins?, there weren't any on the old 15A ones and that was good enough then so must be now, unfortunately there aren't many kids who are fully trained in "safe practices" so won't stick something into the holes, or pull a plug out with their fingers underneath, so these simple and cheap measures were taken.

Safety is continually being improved, RCDs being an example but there are many more, how anyone can argue that supporting this policy is negative is beyond me!

Greg

Enough of your harping.

Greg, when I want to listen to an asshole I prefer to fart.

I'm sorry, I thought you were doing...

Greg

AND, there is a loophole to these reg's. I'll leave you to find it. I did 10 years ago.

Supporting it is one thing, berating people who find your opinion rather self-serving, another.

Tom

Well as Part P of the building regs was only written last year, the wiring regs have been re-written maybe half a dozen times in the last 10 years, and I did the City & Guilds at the end of last year, I won't lose much sleep over what you may or may not have found in 10 year old documents that are only fit for burning!. But by all means carry on using 10 year old information to justify your self, after all the world hasn't changed much in that time has it!

Greg

Many VFDs have Radio Interference Suppression (RFI) capacitors connected between both sides of the mains input and ground (earth). Sufficient current may flow through these capacitors to trip sensitive RCDs. If this is a problem, RCDs are available which have higher trip thresholds.

Jim

On a similar note, how many of you have received

a) a 240V belt in your lifetime b) more than one 240V belt c) died of it?

Regards

Pete

Don't read what you want to read, read the whole. There is a loophole in the reg's and it's still there right up to the new ones, and it's not to justify myself. I didn't write the bloody things but I have to interpret them.

Inland Revenue write the tax laws but some people pay sod all a year and others pay a fortune, still same laws governing all. Some are just better at reading the small print.

One thing I do know is that if I had to call anyone in to check any wiring, you sunshine would be the last pedantic person I would choose.

Not strictly 240V as per your question, but: when I first set foot in a moulding shop back in the 70's to 'learn' a bit alongside a maintenance engineer, he told me to hold one hand on the control cabinet and another on the machine bed while he checked an electrical fault, and tell him if I felt anything..... I was 16 and na=EFve enough to do what he said - once:)

Peter

True, but the law requires standard 30mA types when they are required on socket outlets.

Greg

But you choose not to tell us what it is, yeh, right.
