摘要： A compact and economical clamp assembly for securing a cover plate to an open front electrical panelboard box having mounting flanges. The assembly includes an insulating sleeve surrounding a screw, both of which extend through a hole in the cover plate. The screw has a slotted head, a reduced diameter tip and an intermediate threaded portion. The sleeve has a recess to receive the screw head and a pair of diametrically opposed slots extending from a mid portion of the sleeve to one end. The screw is positioned so that the slots of the sleeve overlap a substantial portion of the threaded portion of the screw. A nut, threadingly engaged with the screw, has two wings which protrude through the respective slots of the sleeve. A clamp member, having a camming end and a clamping end, is pivotally connected to the wings. A torsional spring biases the camming end of the clamp member into contact with the cover. As the screw is turned in a predetermined direction, the nut advances toward the cover, drawing the clamping end to the cover to secure the cover plate against the mounting flange of the box.
摘要翻译：一种用于将盖板固定到具有安装凸缘的敞开的前电板板箱的紧凑且经济的夹紧组件。该组件包括围绕螺钉的绝缘套管，两者均延伸穿过盖板中的孔。螺钉具有开槽头部，直径缩小的尖端和中间螺纹部分。套筒具有用于容纳螺钉头的凹部和从套筒的中部延伸到一端的一对直径相对的狭槽。螺钉被定位成使得套筒的槽与螺钉的螺纹部分的大部分重叠。与螺钉螺纹接合的螺母具有穿过套筒的各个槽突出的两个翼。具有凸轮端和夹紧端的夹紧构件枢转地连接到翼。扭转弹簧将夹紧构件的凸轮端偏置成与盖接触。当螺钉沿预定方向转动时，螺母朝向盖子前进，将夹紧端拉到盖子上，以将盖板固定在箱体的安装凸缘上。

摘要： A meter box and a uniquely designed cover molded out of a substantially rigid plastic material is disclosed. The meter box comprises an open upper top with an upwardly extending rim member. On the inside surface of the meter box are means for supporting a cover forming a ledge member. The cover is arranged and configured to rest on the ledge confronting the rim of the box so as to substantially close the open top of the box. Disposed on the exterior of the meter box are a plurality of anchor tabs. A horizontal member is disposed between two anchor tabs adjacent the top of the meter box which enables the box to be secured in concrete and the like.The cover may be a substantially round member or may comprise first and second sections and means for rotatably joining the first and second sections together. The first section having outwardly extending protrusions which engage slots on the meter box so as to render the first section substantially immovable therein. The second section having an opening which enables the user to lift the second section off the top of the meter box and move it about the rotation means whereby the meter box is selectively opened and closed. The meter box and cover of the present invention have particular utility because of the ease of construction, and beneficial cost versus strength ratios.

摘要： A socket for a watt-hour meter is provided with a manual by-pass device to prevent interruption of power to a load when the watt-hour meter is removed from the socket. The manually operable by-pass device comprises a slider having a pair of contact bridges mounted on a body portion of the slider. The slider is mounted on an insulating base of the by-pass device for reciprocable movement. The bar is supported by contact brackets which are connected to line and load terminals of the meter socket, the slider being reciprocably movable to provide selective engagement between the contact brackets and the contact bridges when the watt-hour meter is removed from the socket.

摘要： An electrical switch assembly having its component parts arranged so a maximum number of the common parts can be used in a flush mounted control station or a surface mounted control station with either of the control stations having rectilinearly moving or rotatable switch operators. The assembly includes components which operate on selected centers so the components may be selectively arranged to be used with two different switch covers, two different type switch actuators and with or without a pilot light. The components also are arranged so the rectilinearly movable operators may be interlocked or made to operate alternately and the rotary operator to be programmed to operate in a two or three position mode of operation.

摘要： A system and apparatus for selectively connecting one of a plurality of sources of electrical power to a load. Apparatus is furnished to be plugged in intermediate an electrical watt hour meter and the meter receptacle normally provided in a typical electrical power utilization system that is usually designed to handle a single primary source of power. The apparatus provides for selective connection of the load distribution center to the utility power line or to another source of power which might reasonably be termed an auxiliary power source. The apparatus may easily be made to be tamper proof by the inclusion of appropriate locking seals. Further provision is made for manual switching or fully automatic operation including the energization of an auxiliary source of power and connection of the auxiliary source to the input terminals of the load distribution center. Suitable devices for sensing the existence of voltage are included to provide signals indicative of a need for selectively switching the input terminals of the load distribution center between one source of power or another.

摘要： The present disclosure relates to a distribution board bus bar module having a leakage current limiting function, in which a current leaking from a bus bar module used in a distribution board may be limited by expanding an area of a bus bar connected to a neutral line among bus bars of the bus bar module used in the distribution board, and thus the risk of electric shock to the human body due to a leakage current can be minimized.
