Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
An electrical fitting for mounting over embedded conduit ducting comprising a base having two ends, means for passing high tension wires through said base adjacent a first end, separate means for passing low tension wires through said base adjacent a second end, walls defining an open compartment surrounding said means for passing high tension wires, said walls being fixedly connected relative to said base, a high tension outlet mounted within said compartment to substantially enclose said compartment, and a cover mounted on said base, said cover being provided with a window matching said high tension outlet and a means for the outlet of low tension wires remote from the window.
Claim 2
Dependent Claim
110 words

Claim 3
Dependent Claim
46 words
The fitting of claim 1 wherein the base is upturned to form a pair of side walls connecting said ends, and said compartment is formed between said side walLs and a pair of spaced ancillary walls at right angles thereto fixedly connected relative to said base.
Claim 4
Dependent Claim
45 words
