Maybe rather than banning some users for a relatively minor offence or first time offence, there should be an area where they can post but not interact with the rest of the forum whilst they serve their time!!
Guys,
As we know, for switches/cables/isolators etc, you need to multiply your Voc values by 1.15 and Isc values by 1.25 to calculate the relevant max values for suitable protection. However, does this apply to MPPT or Max DC voltage/current input values on inverters? Any thoughts?
Thanks
Andy

Bit of a boring subject, and this form is a pain in the arse. But does anyone know who has filled one out before, that in section 10 " Employer or sponsor endorsement and recommendation ", does this section have to be filled out if you are a self employed subby?? If it is, can it be filled out...
I've been asked to go out and look at a job - wiring in a Heat Mat to go under some tiles (bathroom I think, but not been out to visit yet.)
Firstly, I've never done one of these before, so any pearls of wisdom would be greatfully received.
Secondly, I'm assuming that a 'Park Home' (static...

Hi all, i would be grateful if i could pick your brains for some sections of the EICR report form that i am a little unsure of.
1. If you have cables concealed in walls or partitions without 30mA RCD protection is this a code 3?
2. If the service fuse is sealed, is this a lim or N/V and is...
Why have section 7 - 'observations and recommendation for actions to be taken', when we now have 4 pages of 'inspection schedule'.
Also this further investigation required tick box. Am I right in saying that if you've identified something as a deviation, then no need to tick as you've...

e.g
Health Safety
Installation techniques

Hi, I've been asked to carry out a PIR on a Mobile Catering Van. As I haven't done one of these before, am I right in thinking that I complete as much of the forms as I can, just highlight the fact that the supply is from a generator and mobile? Schedules as normal using the generator for live...

If anyone needs to know anything about Surge Protection Devices and the Amendment 1 addition of Section 534 there is a review of a training video on my blog.

Have been installing new 20 amp radials for socket outlets and lighting in a newly built office space in a small commercial unit. The new build office is part of a much larger building, and although it has its own CU, this in turn is fed from a 3 phase DB situated in the warehouse area, which in...
