Move wires to different breaker with same amp rating?
Try different tester?

Test wiring box-by-box to locate the reversed connection.

Check each box for Hot and neutral:

SOURCE: Understanding Outlet Circuit Test Results

open ground=ground wire (green) is not connected to the circuit box ground or to the earth ground.
(there should have steel rod place in the ground by the local electric company, and gtound wire is connected to that rod).
Open Neutral= same as open ground. unless you are testing 240V, which have 2 hot (110v) and a neutral (0V).
Open Hot= open 110v line (black)
hot/ground reversed= if you understand the above, then this sould be self explaintory.
same a hot/neu. reverse.

if you don't understand how electric wiring works, My suggestion is to stay out.

How to fix hot/ground reverse outlet


The black and the white wires on those plugs are reversed. Turn the power off for those plugs, and swap the wires. The black wires go to the brass colored screw, and the white wires go to the silver colored screws.

Installing arc fault interrupter with ground fault


Question is vague. Arc fault and ground fault are slightly different.

Are you installing arc fault breaker?
http://waterheatertimer.org/How-to-wire-GFCI.html#arc-fault
http://waterheatertimer.org/How-to-replace-circuit-breaker.html

Code says Maximum 12 boxes per circuit breaker.

Arc fault breaker and GFCI outlet in bathroom?
>>> do not connect this way.
Do not install 2 fault protections on same circuit.
Install the arc fault circuit breaker, and then remove bathroom GFCI, and replace with ordinary outlet, or switch-outlet.

How many outlets can be connected to a bathroom GFCI?
It depends on total boxes on circuit.
Count the boxes. Max 12 boxes per circuit breaker.

How many amps can be connected to 15 amp device?
15 x 80% = 12 amps
Electricians use 80% rule to calculate safe maximum

New intermatic T101 timer problem - timer is not


Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

Add a comment any time.

What does open neutral on my gb circuit tester also hot/ground reversed mean


An open neutral means that neutral, or common wire is not connected somewhere. If for example you test a outlet in a room, and the tester shows that you have an open neutral, Then somewhere along the circuit the neutral is not connected properly. In rooms most outlets are connected in series to each other, so if you have an open neutral in one outlet, it can affect all the other outlets too.

Hot/ground reversed means that the hot wire and the common wire are installed in the wrong order.on the outlet,you have a hot side (black wire)and a common side(white wire)and the hot wire is installed on the common side instead of the hot side and the common is installed on the hot side.This show up on the tester this way because the common and ground tie into the same bar in the panel.

Fix the open neutral first as this can show incorrect reading on the tester on all outlets after the open neutral.
