Abstract
A template provides a quick and accurate method for marking locations of conduit entry holes to be formed in an electrical panelboard. The template is a rectangular sheet that is divided into longitudinal spacer zones, transverse spacer zones, a longitudinal marking zone and graduated marking zones. Each of the marking zones has multiple apertures used in making marks on the electrical panelboard to identify hole locations.

A template for laying out electrical conduit entry hole positions on an electrical panel housing, the template comprising:
- a sheet having a longitudinal straight edge for engaging a wall surface on which the electrical panel is fixed;
- a spacer zone bordered on one side by the longitudinal straight edge and extending the length of the template, wherein the width of the spacer zone in the transverse direction corresponds to the thickness of a support means used to secure the electrical conduit to the wall surface;
- a marking zone extending parallel to the longitudinal straight edge and spaced from the longitudinal straight edge by the spacer zone, the marking zone having a width in the transverse direction corresponding to an outside diameter of a given size of electrical conduit;
- and
- a plurality of apertures formed through the sheet and centered on the marking zone, the plurality of apertures forming a line parallel to the straight edge and designed to receive a tool for marking the center locations of entry holes.
A template for laying out electrical conduit entry hole positions on an electrical panel housing, the template comprising:
- a sheet having a perimeter with a pair of parallel longitudinal straight edges for engaging a wall surface on which the electrical panel is fixed;
- a ¾ inch spacer zone extending the length of the template and bordered on one side by one of the longitudinal straight edges, wherein the width of the spacer zone in the transverse direction is approximately ¾ of an inch;
- a 1½ inch spacer zone extending the length of the template and bordered on one side by the second longitudinal straight edge, wherein the width of the spacer zone in the transverse direction is approximately 1½ inches;
- a longitudinal marking zone sandwiched on the sheet between the two spacer zones and oriented parallel to both longitudinal straight edges, the marking portion having a width in the transverse direction corresponding to the outside diameter of a given size of electrical conduit;
- and
- a plurality of apertures formed through the sheet and centered on the longitudinal marking portion, the plurality of apertures forming a line parallel to the longitudinal straight edges and designed to receive a tool for marking the center locations for electrical conduit.

- and
- a plurality of apertures formed through the sheet and centered on the longitudinal marking portion, the plurality of apertures forming a line parallel to the longitudinal straight edges and designed to receive a tool for marking the center locations for electrical conduit.
- applying the template to the electrical panel housing so that the spacer zone with the width corresponding to the thickness of a support means to be used to secure the electrical conduit to the wall surface engages the wall surface;
- positioning a marking tool inside the desired apertures and marking the locations of the entry holes to be made on the electrical panel housing.
A template for laying out the locations of electrical conduit entry holes on an electrical panel housing comprising:
- a sheet having at least one longitudinal straight edge disposed perpendicular to at least one transverse straight edge,
- wherein the transverse straight edge is for engaging a wall surface adjacent to the electrical panel housing
- a spacer zone bordering the transverse edge of the sheet and having a width in the longitudinal direction equal to the thickness of a support means used to secure the electrical conduit to the wall surface;
- a plurality of apertures formed through the sheet to receive a tool for marking the centers of entry holes on the housing, the apertures variably spaced from the spacer zone by distances equal to the radiuses of a multitude of conduit sizes.
A template for laying out the locations of electrical conduit entry holes on an electrical panel housing comprising:
- a sheet having a longitudinal straight edge disposed perpendicular to a transverse straight edge, wherein both straight edges are for engaging a wall surface adjacent to the electrical panel housing
