This is not a song: Cantore Arithmetic is able to state that the word bible[Bible] equated words in[Inn] the [new[New[knew[Knew]]]] testament[Testament], and the name in word Port equated word known word virtually bringing words on the tip of your tongue to a word location for AR the letter of the Introduction to individualize eh from word are. The word version is word defined: : an account or description from a particular point of view especially as contrasted with another account. There is an entire world[World] that has read a particular version[word experienced?] and the the word version is word accounted for[fore[4]] however word four is more than word too, so new mathematics at word mat equated words wipe-your feet.
The technical word interruption equated word complete a the Garden of word named Eden should have word sufficed and yet this word earth is named word Earth as the Garden is of word eden[Eden]. Words the plot to this word sufficient is not word mandatory or words wipe-your feat[feet] as word garden places word to text and the word Garden has been word left, so, where is the house? Where is the establishment for words Save the Farm?
The laws that have been made just in my country not tis of-thee have thrown word feet[Feat] to the dogs and rose word house to the rib. The word manufacturer is word creator and your word image in word created states word top. So yea you Men of Shakespeare, the written to the Pen is the avenue of your disregard. Yea you Men of Fear, your prowess of attention has parted my bladder, the rose is not a thorn however this dignity of reality equated word faith has dropped nothing more than the ball of your horror. So less you fragrant words and your morsel of a body, the shoulders of the clap and the awaiting dressed map, there is no alien in this vice, and yet, the tactile will leave your Island and manufacturer nothing as Airplanes and Ships are defined.
Your failure to appearance to staggering book is the attention to the morsel and the cookie it Rook. Place no-hand to those that have no appearance for should an it be more than an if your eyes are mortal and the lens is took. The brain in your foot as it travels to your soot, the blackened representation of nothing more than the put, so as you fragment without the word dignity, sentence Well and the s will bring you to Hell.

People or word persons[Persons] whom wish to change the World have word immediate text to test the minds of a psychiatrist[A psychiatrist is a physician who specializes in psychiatry.

So, thee American Medical Association of Psychiatry[EI] as word lettered AR in equated word condition[horse[three-day eventer[‘B’ Graduate.]]] is able to state that the Hippo is equated as words the 5th Element due to the convenient 5th tusk rising beneath in word perception equated word tongue and bringing the Sphinx the word match as words Hippocampus and satisfying the REM sleep[Sleep[SLEEP]] as Jerry Dyer now words Mayor of Fresno had an over-dying word said to the animals and those four teeth going the correct directions: 👇👈, 👆👈, 👆👉, 👇👈.

DETAIL Ground Cable Support
GENERAL REQUIREMENTS
DETAIL "B" Grounding Requirements
Each Power Circuit Breaker or Power Transformer having a bushing Voltage Transformer on the tank shall have the Voltage Transformer provided with a separate ground lead, independent of the Breaker Frame or Transfomer Case grounding leads.
Multiple voltage Transformers on one unit can have their grounding leads bussed together in convenient runs, i.e.,
for a breaker with 6 voltage transfomers, the 3 on each side can be bussed to a separate single tie into the ground bus and possibly follow the inter voltage Transformer conduit run.The ground cable shall be supported as shown on this dwg. The grounded end of the ground switch of the Voltage Transformer shall be electrically connected to the ground terminal on the cabinet. (See Detail "B"). When adding Voltage Transfomers to existing installation, provide an independent ground lead from the Voltage Transformer or group of Voltage Transformers and connect to the nearest exposed station ground cables.
This sheet supersedes EDS 102825 "Requirements For Grounding Bushing Voltage Transformer" .
