I went on a service call at a Hotel they said 90% of the outside lights where out.

I found tripped breakers and started looking for faults, this turned out to be tough, many boxes in the ground had been buried.

Here is one I found under 10" of bark mulch.

It measures 2.5" x 2.5" x 4.25".

How many 10 AWG conductors can we put in here?

Anyone want guess how many 10 AWG conductors where in this box?

Guess high.

Shockme your good. [Linked Image]

It was 27 - 10 AWG solids.

14 conductors entering in each raceway, all spliced.

There are about 15 of these boxes all about the same, a few have only 16.

7 - 120 volt circuits and 2 - 2777 volt circuits.

Any one notice the holes in the box are 3/4"?

A: A yardstick.

Q: What do you call a strip of wood marked in 100 one-centimeter increments?
A: A paint stirrer!

It's my wife's tape measure, she does not shop at job lot, I am thinking the "Dollar Store". [Linked Image]

It won't even make a good paint stirrer. [Linked Image]

Q. What's brown and sticky?

A. Another stick!

Having a dual metric/inch tape is real handy here, for obvious reasons if your brain thinks in imperial. Funny thing is, nearly 200 years into the metric experiment in France, the inch (pouce) is still understood, you can buy potatoes in the market in livres ( pounds) and most plywood comes in 4' x 8' sheets, ( made in or for the US market). Had a laugh one day, saw a Brit strolling toward the builders' merchant office with a piece of unmistakable orange Brit pvc soil-pipe on his shoulder. UK = 110mm OD, 4" bore. French 100mm OD, 94mm bore, and totally incompatible. Hope he hadn't fitted too much already! One of my favorite things is to pretend to study a product, eavesdropping on some hapless Brit mangling the French language, (or just speaking English very loudly! ( "AVEZ-VOUS FOUR INCHES!!" ), while the long suffering assistant wishes he was someplace else, like on the beach in Cap d'Adge!
