Steps to run conduit through exterior wall: –

  1. Firstly, drill a hole in a wall

To set up an outdoor wiring, you need to choose the right size of drill bit and drill a hole in the wall. The size of the hole should be enough to hold the conduit.

  1. Now bend and cut the conduit

You need to bend the conduit with a bender if you want EMT or non-flexible conduit. You can also use fittings with 90 or 45 degree angles if you do not have a bender.

You can use a pulling ell for 90-degree bends as they have a removable cover. You can use a propane torch for heating the pipe so that it can bend to the angle required. This is for PVC conduit.

Measure and conduit- Take the measurement and after that cut the conduct according to that. Use a hacksaw to clamp the conduct.

Use a saw which is circular for thick metal conduit as the cut will become smoother.

You can use a screwdriver and smoothen the edges with its blade.

Use a plier to cut any edges on the outside.

  1. Now glide the conduct through the hole

Pass the conduit across hole that is there in the wall. You will need an ell puller for this. You need to make sure that the space is enough for the conduit in the drill hole of wall.

Make sure that there is no water before you glide the conduit through the wall. If the water is there near the wires, you should make sure to add a GFCI breaker.

You will need a box extension in case you are using an electrical box for the conduit.

  1. Attach the conduit support

If you want the conduit running through the walls, then you should make sure that it is supported with conduit hangers.

The hangers need to be at least 10 feet apart. Make sure to measure and mark the place of the hanger. These hangers can be attached using a screw.

  1. Now you need to drag the wire through conduit

Use a tape to drag the wire through the conduit. The conduit and its connectors along with wires will glide through the hole which is there in the wall.

  1. Secure the gaps of wall using caulk

You can now use a silicone caulk for securing the connection between hole in exterior wall and conduit.

  1. Plough a trench

Now this step is optional. You will need to plough a trench in case you are putting a wire underground. You need to contact your municipality before you plough a hole.

Only they will be able to inform you regarding the water and gas lines. Dig a hole around 25 inches in depth using a spade.

You can use a trenching machine in case you want the wire to be longer. You can also rent these from any local store instead of buying them.

  1. Now when you are done running the wire through the trench, you need to put sand as a layer because it will act as a warning for any diggers trying to dig that area in future.

Also, do not forget to add a red tape over it for caution. Now add soil on the top.

Installing an EMT conduit

  • EMT conduit is used for installing electrical conductors in residences. Mark an area which you want to layer with the conduit.
  • You need to measure the length of conduit which you will require after you are done with the marking.
  • You can use a hacksaw for cutting the conduit. You can use screwdrivers or pliers to smoothen the cut.
  • Now attach the fittings to hold the conduit and drag the wires through conduit by using a tape.

Electrical wires are required to be in conduit to protect from sunlight and rain. You can use any form of conduit whether it is made up of metal or plastic according to your requirements.

Electrical wires can cause a lot of harm that is why it is necessary to protect them so you can conduit them. PVC conduit or EMT conduit last longer.
