Be Yourself

Image
Life is too short and too precious to not enjoy; even if the alternative is the norm.

Losing my Dad when he was 69 (I was 40) and my Brother when he was 45 (I was 43) made me very aware of that.

I'm now older than my brother was when he died. I've outlived him.

I'm determined to live my life to the full, enjoy being me, and I'm going to make sure I leave something for the generations who follow me.

Latex is something I enjoy being in. Many people think it's weird or strange, but you're only here once and you only get the days you're given.


I'm something else

"You're something else" was a comment made on an Instagram post when I shared a photo of my newest suit.

Why? You ask...

Well this is what I went to Corporation in last night.

It's PVC and it came from ASOS. Yes. ASOS. Mainstream clothing shops are now selling PVC!


It was a great night to be honest, apart from the hot and sweatyness of the outfit. Quite a lot of people were taken aback by me in it and there were a lot of people who wanted to try it on.



I also had my fair share of creepys who stared at me, and a few people who wanted photos taking with me in it. I can't think why...

I know this is nerdy stuff, but today I encountered the highest PSC (Prospective Short-Circuit Current) that I've ever encountered on an installation.

23kA was the figure I found, with an external loop impedance of just 0.01A

So, why you ask am I sharing this?

Let me briefly explain.

All breakers have a maximum "breaking capacity". It's a number, usually in a box, on the front of the device. Most domestic ones are 6kA, industrial tend to be 10, 12, 15 or even 25.

If a short circuit occurs which takes the fault current above the breaking capacity of the breaker then the breaker may not actually trip, or it might fail, or the it may trip but the spark will then "hop the gap".
So, what do we do in this circumstance?

Well we could protect the installation with BS1361 fuses, however, that is not guaranteed to get your 0.4 second trip time.

My chosen method is to put an MCCB (Moulded case circuit breaker) with a 25kA breaking capacity into the meter tails. Not on…
