Abstract
A template for locating and marking the positions for conduits entering an electrical panel and the like comprises a rectangular sheet with a series of holes each spaced at distances from the upper and side edges of the sheet to space the centers of different size conduits from those edges. The template has markings leading from each hole to the upper edge at positions indicating the edges of the respective conduits opposite the side edge of the sheet, and the sheet has a ruler scale along the side edge. The template is used for the step-by-step marking of successive conduit locations on a panel using the respective holes and markings in conjunction with a datum line on the panel.

A template for laying out electrical conduit positions on an electrical panel and the like comprising a sheet formed with a pair of orthogonally disposed straight edges, a plurality of openings formed through the sheet at different distances from said edges respectively for marking the centers of different size conduits, the spacing of each opening from the respective edges being related to a particular conduit size so as to space the center of the conduit a suitable distance from lines along which the respective edges of the sheet are placed, and indicia on one surface of the sheet identifying the size of conduits designated by the respective openings, wherein each opening is spaced from each of said edges by an amount corresponding to half the inside dimension of the conduit it designates plus the conduit wall thickness, and wherein the template further includes a marking on said surface of the sheet along one of said edges for each of said openings, each marking being spaced from the respective opening by an amount corresponding to half of the inside dimension of the conduit which the opening designates plus the wall thickness of the conduit.
A layout template for locating and marking the positions of electrical conduits on an electrical panel and the like comprising a rectangular sheet having an upper edge and a side edge, a plurality of holes formed through the sheet to represent the centers of different diameter conduits respectively, each hole being spaced from the side edge and the upper edge by an amount corresponding to the inside radius of a respective conduit plus the conduit wall thickness, markings leading from the respective holes to points on the upper edge of the sheet each spaced from the respective hole by an amount corresponding to the inside radius of the respective conduit plus the conduit wall thickness, and indicia on the sheet correlating the respective holes, markings, and conduits by size of conduit.
A method of locating and marking the positions for electrical conduits on an electrical panel and the like comprising the steps of;
- (a) providing a layout template comprising a sheet having mutually orthogonal straight upper and side edges, holes formed through the sheet for marking the centers of different size conduits, the holes being located at positions which are spaced from the respective edges of the sheet by distances related to the sizes of the different conduits, markings along the upper edge correlated with the respective holes for marking the edges of the respective conduits opposite the side edge of the sheet, and indicia identifying the respective holes and markings in terms of the conduit diameters;
- (b) providing a datum line on the panel and the like for the tops of the conduits;
- (c) providing a point on the datum line spaced from one edge of the panel and the like for the edge of a first conduit;
- (d) positioning the template on the panel with the upper edge of the template along the datum line and the side edge at said point;
- (e) marking the center of the first conduit through the respective hole in the template corresponding to the required conduit diameter, and marking a further point on the datum line corresponding to the position of the marking along the upper edge of the template correlated with said respective hole;
- (f) providing another point on the datum line spaced from said further point by a distance suitable for positioning the edge of a second conduit;
- (g) repositioning the template on the panel and the like with the upper edge of the template along the datum line and the side edge of the template at said another point, and (h) marking the center of the second conduit through a separate hole in the template corresponding to the required conduit diameter.
