Pictures of the week - one for each working day!

A few pics for fun. If you don't like commercially type photos, click the back button


A plumbers extension lead.
He wondered why his boiler wasn't happy when
he commisioned it using a plugtop.....

Flicky fluorescents in a large office, all the fittings are like this.....

Here you can see 169amps being drawn on a 300amp rated submain.
This board used to be the main board before a mains upgrade and re-locate.
The larger black cables in the first pic ARE THE SUPPLY TO THIS BOARD.
The incomer on this Ottermill board is side mounted.

The cover was removed from this panel for some other works on site,
but thought I would have a quick play

59amps on an outgoing way from the same board directly feeding a fixed rated power factor correction capicitor.

The next photo is not embedded - click the link to see it.
This is the current being drawn by the submain with the power factor correction capacitor turned OFF.
Thought you could have a guess at what the current would be before seeing it.
Remember, 169amps is being drawn by the submain with the power factor correction capacitor turned ON,
the capacitor drawing 59amps itself......

I hate to be pedantic but a PF correction capacitor bank connected to that board would not affect the outgoing current of a sub-main - the kva load would still be the same. The PF correction can only reduce the reactive power on the feed to the main board in the picture.

The plugtop police will be around shortly!

IT IS the main feed to it. The incommer is side mounted on this older style OTTERMILL MCCB board.

I can assure you that the load is pretty constant, and the 169 is what is being CONSUMED by the MCCB board, the 59amps being drawn by the CAP.

Sorry Lec, I thought the one you had the clamp on was an outgoing sub-main.
