SW, the standard you need to comply with is BS EN 60439-3, part 3 of the standard you refer to has yet to be published i believe, either way, BS EN 60439-3 valid until Nov 2014. BS EN 60439-1 states; TYPE-TESTED AND PARTIALLY TYPE-TESTED ASSEMBLIES The Standard IEC 60439-1 differentiates...

The oven pilot is wired from the thermostat, so when the oven stat is closed the pilot light is on, if this remains on all the time then the stat will need replacing, unless of course there is no heat.

The shunt diode protects the transformer in the case of a faulty rectifier, it wont effect its function by removal, old and cheap models probably wont have them. If the rectifier goes O/C and produces AC instead of DC it can damage the transformer as the fuse may not blow, the shunt diode is...

It's a shunt diode. The other is a rectifier.

Really, shall we carry out a touch voltage exercise, then you will see R2 determines the touch voltage ---------- Post Auto-Merged at 23:48 ---------- Previous post was made at 23:46 ----------

Ah, i said determines, not limits :)

Very Interesting

Incorrect R2 determines touch voltage :)

Work at this time of night, do you sleep lol

Well the Gentleman who's job it is to update GN3 is aware of the scenario, we will wait and see. Paul, touch voltage's may be much higher than 50V, BS7671 only considers touch voltage where supplementary bonding is required and other special locations. The 50V limit comes from the manufacturing...

Its testing the tripping mechanism and the disconnection times at a given imbalance. It tests the RCD. Ill give you a scenario that many advise yourself included. The RCD dosent trip when testing, " have you disconnected the load from the RCD". So the connected load stops the RCD from working...

Steps, this is called strapping the RCD, you will find reference to it in later versions of Fluke and Megger manuals. Your testing the RCD, not the connected system. This is also the method to use where a high Ra may be present. You may find this in the new GN3, as they are aware of the 50V...

Sorry Paul The other option we have currently is to turn the area of the premises being used into a Group 2 Medical Location, see section 710, BS7671:2008 Amd 1:2011, the cost would be exorbitant, and the complexity of doing this in the environment would be highly disruptive. Group 2, or...

Are you sure it's class 2?

My point is you don't need to do anything, your just giving a quote, no contract no work. Contract = Work for gain or reward EAWR Guidance 2 The Regulations are made under the Health and Safety at Work etc Act 1974 (HSW Act). The HSW Act imposes duties principally on employers, the...

Its about protecting your Tenant's and yourself, i know what i would do. :)

There is no direct statutory requirement for Electrical inspection and Testing, though there is a requirement for it to be safe and maintained. How do we ensure that the electrical system is safe, simple we have the installation Inspected and Tested by a competent electrician at regular...

Your getting confused bulrushes are straight:)
