Three phase DB, water, you can geuss!

Well, having just joined up i thought id post some of the work i get involved with and what not and generally introduce myself!

Im Jamie, I'm 22, and an industrial/commercial electrician in the southwest.

Generally i get alot of fault finding and reactive installation work to do, and I'm just in the process of going self employed now.

But anyway, i went to a site the other day to carry out a EICR and this is what was awaiting me! A 50a TP-N DB that was mounted next to a garage door and was been leaked on by the roof!

As you can see its a bit of a mess!

Well, it turns out that <3 months ago a large electrical contractor in the area had fitted a new supply to the forklift charger (50a single phase), but didnt have any cable big enough so they doubled up 2x 6mm cables for L,N,E, *rolls eyes*

It also turns out the MCB was upside down, causing mass confusion to the guys on site as it kept tripping out due to only been a "b" type

Earth didnt quite fit in the terminal it seems -

So I isolated the board and made safe and the client agreed to let us install a new fuseboard and sort out the cabling issues!

Found a burnt out lighting circuit then realised this might have something to do with it -

So on with a new DB and enclosure,

I elected for a GRP IP65 enclosure with an eaton TP-N DB inside with all cables + conduits passed through the GRP enclosure with stuffing glands and suitable washers with weather proof glands going into the DB.

New supply for the forklift charger -

Lighting Circuit renewed -

There we have it,

Hopefully they are all up to your exacting standards, and C+C is welcome!

Jamie

Welcome to the forum....

By the way, there's nothing wrong with parallel supplies, so no need to roll your eyes to far...lol!!!
For a 50A supply requirement they could of used 2 X 4mm, easier to pull and all!! lol!!

Now explain to me why there is nothing wrong with it? I dont quite see it?

If you have 2x cables capable of 30a each, running a 50 a load, and one leg fails, you end up with one cable running 50a thats only rated to 30a?
