We have nearly 300m of this crap being installed at the moment, colour and brightness consistency across the 12 zones was a big concern.
We were advised by the manufacturer that anything over 8m will start to fade at the end of the tape as the voltage drops.
As a result we have run a feed...
If this is a genuine change then throw it back at them, a nicely worded email explaining the additional testing requirements and paperwork charge of £--- per unit might focus their minds a little.
It's not FP or P clips or tray, it's the combination of the three. The purpose of any exam is to prove capability but it has to be contextualised. You may as well give the lad a chisel, some marble and see if he can carve up a David; he's as likely to be asked to do that in his career as to...
If you're being asked to use P clips on tray then you need to seriously question the veracity of this educational institution. Just why?
Some clown pulled me for not using metal cable ties on tray, tray above a 60min fire rated plasterboard ceiling at that. Any incident that causes those cables...
So you have a total of 550w @ 230v, you shouldn't be challenging a B6 on overload but clamping it can confirm this.
Do you have an earth leakage figure for the floods/drivers? Could it be cumulative working earth leakage.

Find it in use regularly, mostly it's being ripped out as part of a refit/refurb but it's definitely still out there. It does then to be odd bits rather than a full installation.
My experience has found that in lofts, and where exposed to heat cycling, it becomes brittle as in the OP but, if...
What are you determining the demand for?
Domestic - use the OSG. It's written to cover an average domestic dwelling.
Commercial - use your noggin. You need to have a decent understanding of the end use and from there can determine your own realistic demand.
Industrial - above my pay grade and...
30 mins a light is perfectly acceptable especially on a finished ceiling.
I do love how some people know how long other people's job "should" take. You sir have the makings of a real nightmare customer.
Not being critical at all but it sound like you're too cheap.
7.5% GP seems a lot of work for little return.
In an ideal world you should be squeezing your less stress jobs and whittling out the high workload-low return ones.
Easier said than done though.
It's a doddle when you know what you're doing, a couple of hours work for a spark and most of that testing before and after then preparing the certification. I don't do domestic work but I don't think it would require local authority notification but you will need a Minor Electrical Works...
portable appliance testing, and that's self explanatory.
In an ideal world, as your visit is booked in on site, the customer has arranged for each department to collect all their appliances in a convenient location where the confirm the presence of all items against last year's list, delete...
