The current electrical setup in the space is inadequate for our needs. We're proposing making some small changes.

Problems

  • Overhead shop lighting is on the same circuit as several existing shop outlets. The server room lights/receptacle are on the same circuit.
  • Switch for shop lighting is in a poor area.
  • Shop area needs more outlets/circuits.
  • Admin light switch in poor location
  • Not enough power in the front room for proposed Laptop Bar area. Another 20A circuit would provide for the immediate needs.
  • Loose and charred outlets need to be replaced and covered properly
  • Some 4SQ boxes missing cover plates.

Solutions

Overhead lights

  • Overhead lights should be on their own circuit, and switch should be in a more accessible and logical area.
    • Add additional breaker/circuit to breaker box dedicated to overhead lights.
    • Propose mounting the switch on the support column in the middle of the unit.
    • Shop in-wall outlets can be moved to a new circuit utilizing all existing conduit.

Materials needed

  • Length of conduit to go from switch on column to existing junction box.
  • Length of conduit to go from breaker box to existing junction box.
  • Switch
  • Wire

Add Circuits to Shop Wall

Green: Existing, Red: New Work.

  • Utilize existing conduit, outlets and boxes.
  • Add additional conduit to run from breaker box to first box.
  • Add additional boxes.
  • Add 2(?) new circuit breakers to breaker box.
  • End result is 4 boxes with two outlets each, on two different circuits. Additional conduit/boxes could be added extending further along shop wall towards the front of the unit.

Materials needed

  • Approx. 100ft each of black/white/green 12 AWG NHHL wire
  • Approx. 32ft of conduit (4 8ft sections)
  • Two 20A circuit breakers

Admin Room

  • Move switch for Admin Room lights from front room to wall inside entrance to the Admin Room.
  • Run new circuit dedicated to Admin Room outlets through existing conduit.
    • Existing 3/4" conduit has 6 (7?) 12 AWG conductors. Code allows up to 18 conductors in 3/4" conduit.

Materials needed

  • Old work box
  • Approx. 10ft of flex conduit to go from switch to junction box in ceiling
  • Approx. 100ft each of black/white/green 12 AWG NHHL wire
  • One 20A circuit breaker

Front Room "Laptop Bar"

  • Run new circuit dedicated to laptop bar outlets through existing conduit.
    • Existing 3/4" conduit has 6 (7?) 12 AWG conductors. Code allows up to 18 conductors in 3/4" conduit.

Materials needed

  • Approx. 100ft each of black/white/green 12 AWG NHHL wire
  • One 20A circuit breaker
  • Boxes, outlets as needed (TBD)
