Line 3: Objectives : * Bring the Emergency ~~Top~~Stop control into use for the 3-phase tools (as appropriate) * Separate the 16A sockets for the [[tools/bandsaw\|Bandsaw]] and [[Tools/EMP235ic\|MIG Welder]] onto individual circuits * Separate the [[tools/pillardrill\|Pillar Drill]] and [[tools/pedgrinder\|Pedestal Grinder]] onto individual circuits * Provide a new 16A socket for the [[Tools/AT260SPTPlanner\|Planer -Thicknesser]] * Provide capacity for a new 16A socket in future == Current State == <Gallery mode="packed">▼ File:DB3A Overview.jpg\|Overview▼ File:DB3A Top section.jpg\|Top section detail▼ File:DB3A Bottom section.jpg\|Bottom section detail▼ File:DB3A Top left.jpg\|Top left detail▼ File:DB3A Top right.jpg\|Top right detail▼ File:DB3A Bottom left.jpg\|Bottom left detail▼ File:DB3A Bottom right.jpg\|Bottom right detail▼ </Gallery>▼ The existing board is based on 2 ~~25mm~~35mm DIN rails, each of 250mm length. These are mounted on a removeable back plate. Three 4-pole NC contactors are fitted, but only being used as junction blocks at present. The primary cable entry is via the trunking at the bottom of the box, with a single armoured cable entering on the top-right side. Line 33 ⟶ 26: * Wire new 32A breaker to new E-Stop contactor with 10mm conduit cable * Install new earth block onto wall of DB3A. Bond cabinet and door to earth block. * Connect ~~metal~~[[tools/metallathe\|Metal ~~lathe~~Lathe]] wiring directly back to MCB 5L1/L2/L3 in Main board - 4-pole junction / 20A * Install new 16A 3-phase RCBO's for ~~Piller~~[[tools/pillardrill\|Pillar Drill]] and [[tools/pedgrinder\|Pedestal Grinder]] * Install new 16A 1-phase RCBO's for [[Tools/EMP235ic\|MIG Welder]], [[Tools/AT260SPTPlanner\|Planer -Thicknesser]] and spare circuit * Install new 6-way DIN rail terminal block for neutral connections * Install new 4-way DIN rail terminal blocks for L1, L2 and L3 switched connections * Pull new 2.5mm cable through for [[Tools/EMP235ic\|MIG Welder]] socket. Remove old wiring from shared 16A box. * Install new 20mm conduit in ceiling to centre pillar. * Pull new 2.5mm cable through for [[Tools/AT260SPTPlanner\|Planer -Thicknesser]] socket. Install new 16A surface socket on ~~centrel~~central pillar. == Photos and Drawings == ▲<Gallery mode="packed"> ▲File:DB3A Overview.jpg\|Overview ▲File:DB3A Top section.jpg\|Top section detail ▲File:DB3A Bottom section.jpg\|Bottom section detail ▲File:DB3A Top left.jpg\|Top left detail ▲File:DB3A Top right.jpg\|Top right detail ▲File:DB3A Bottom left.jpg\|Bottom left detail ▲File:DB3A Bottom right.jpg\|Bottom right detail File:DB3A dimensions.jpg\|DB3A dimensions File:DB3A new layout.jpg\|Proposed new layout File:Detail_db3a.jpg\|Board DB3A - completed File:DB3A label.jpg\|Board DB3A internal label ▲</Gallery>
