    Hello everyone and thanks In advance for your help. I have a 3-car garage which is becoming more of my shop. I have several large woodworking machines; the biggest motor I have is 3 HP and I have two of those. The main service panel is on the outside of the garage wall. It is a 200 amp panel...

    I'm about to install a 100 amp subpanel directly next to a main panel to be used as a generator panel during power outages. I'll connect the two with probably a foot of 2" conduit and run the 100A feeders along with the dedicated circuits through that into the sub. I plan to splice extensions...

    Hello, The previous owners of my house had power ran into the backyard. I believe it was for an above ground pool pump and some lights, which are now gone. They ran 6 12-awg wires (1 blue, 1 red, 2 green, 2 white) underground through conduit. I want to use this existing run to power the...

    Can anybody tell me if there are any restrictions/requirements or best practices for running the supply wire from a main service panel to an adjacent sub-panel? Here are my options: Option #1 and #2 - Sub-panel main lugs at top of panel. Service wire can enter from side of sub panel or...

    How should conduit (PVC in this particular case) terminate at or above a drywalled ceiling? Specific case is a surface-mounted subpanel in an attached garage. Would it just be a hole in the ceiling drywall, through which the conduit passes and then simply ends with the wire coming out?

    I keep dragging my feet on this. To make a very long story short, I need to determine once and for all where my garage subpanel should go. This will just provide a pair of dedicated branch circuits, as the only outlet in the garage is in the back wall and is shared with the bathroom on the other...

    I hired a pro electrician to add a 4-wire spa panel with a GFCI breaker. Because the main panel was so far away, the disconnect panel is wired to a closer existing subpanel. The GFCI test and hot tub seem to be working fine--the spa panel's isolated neutral bar is used correctly, etc...

    I am installing a 100amp subpanel in my attached garage. The panel is 45 feet (actual wire length) away from the 200amp main panel which will be running through a finished basement against an outside wall. What size wire should I use? I presume that the ground has to run back to main and there...

    I want to put in an 70 amp subpanel on my second floor. It's about a 55ft run from the basement panel. Initially I thought #4 romex would be sufficient (I see they limit the romex to 60°C now and Table 310.15(b)(16) shows that #4 is max 70a at that temp), but all the #4 romex I can find has a...

    Hello all – I’m looking for some clarification on wiring my newly-built detached garage. At the outset, I’ll say I am not a complete novice with electrical, as I wired half of my house myself and installed an automatic standby generator myself as well. I’ve done a lot of minor electric work...

    Hi, I'm planning several projects over an extended time period which all involve electrical work to various points in my property. An example is i'm getting a new well put in soon; but sometime next year I will be putting in an outbuilding with a subpanel. Even farther out will be a standby...

    I am installing a 100 amp subpanel in my attached-detached garage (detached garage that shares a roof with my house), which is being fed by my main service panel. Most of the branch lines from my main service panel go through a knockout into the house and one branch goes through PVC conduit to...

    When is a bonding bushing required? See picture attached. Should I use a plastic bushing or a bonding bushing in this situation? Three #4 wires and one #8 wire (for ground) are entering a subpanel through 1" PVC conduit with a PVC male adapter and a locknut. Thanks

    I want to go overhead to a subpanel on a utility pole. I already have the #6 Romex wire in my attic (no longer in use), so I will make a junction in the attic, run to an eave, and mount a box on my home's fascia with the Romex inside. That will also be a junction box. What I want to do is select...

    I have had my external service panel inspected and no problems. However, my inspector took a look at my interior subpanel (which I am doing now and will have inspected when ready) and he said that I needed to put the copper ground wire from my subpanel feed (4 gauge stranded) on the...

    Hi, I’m going to install a sub panel in my detached garage and I would like to make sure everyone agrees I’m doing this the correct way and asking for any ideas for improvement. I’ve recently trenched from the house to the garage and installed 1” PVC Schedule 40 conduit. My main panel has...

    I am installing a sub panel in my house and running the wire through the attic. I am planning to run THNN wire in PVC conduit or SE cable. Since the circuit will be breaker protected I am thinking SE cable is OK. However if I use PVC conduit and pull the wires I can save some money and of course...

    I bought an Eaton 200A main lugs panel outdoor panel to be fed as the service entrance from the bottom with a subpanel feed out the top feed thru lugs. Eaton states in their lit that: "a standard panel can be rotated 180 degrees to allow straight-in wiring of power cables to the main...

    I am installing a 200A main breaker panel as my service disconnect. The Eaton BR816B200RF panel will have feed thru lugs on the bottom. I want to feed a 150A sub panel from those lugs. The subpanel will be 50 ft away in the same building, and have it's own 150A breaker. I would rather not...
