with apertures 82 through which the conductors 81 may be accessed from the lower face of the flange 13 fig1 illustrates a tee 10 on which a plurality of conductors 86 are printed or otherwise established on the upper side of the flange 13 the conductors 86 are isolated from one another and are isolated from the flange by an insulating layer applied to the top surface of the flange 13 additionally the conductors 86 are over coated with an insulating layer to avoid short circuiting the over coating of the top insulating layer may be omitted at points 87 to facilitate connection with electrical contacts or electrical wires making reference to fig1 a conventional grid tee 10 can be fitted with a cap 91 after the grid tee is installed the cap can be made of plastic or metal suitably coated with an insulating layer on its interior the cap 91 is printed with a conductive ink to form one or more conductors the conductors 92 are over coated with an insulating material to prevent shorting against surfaces or edges of the tee 10 alternatively the cap 91 can be structured such that when it is installed the conductor or conductors are spaced away from the lower surface of the flange 13 or cap 16 by temporarily removing the cap 91 the conductors 92 are readily accessible for establishing a circuit with a connector for supplying or drawing power fig1 illustrates a novel grid tee 96 which is extruded or otherwise formed of electrically insulating material such as pvc or other well known thermoplastic or thermosetting material conductors.
