Once you start drawing a certain amount of current, the resistance generates enough heat in the wire to (physically) move it, causing a break in the circuit. When it cools, it moves back and the connection is restored. Backstab connectors on cheap outlets are a common culprit. Use the breaker to disconnect the circuit and inspect your connections inside the outlet boxes, move wires from backstabs to the screw terminals if you encounter their use. | |

| Aug 22, 2017 at 17:36 | comment | added | user74603 | Plugged in a lamp to the 110v and the lamp worked (two prong). I then plugged the laptop into one plug on the box and the power bar into the othe. The laptop would run by itself and one item from the PB would run by it self but as soon as I added more draw by turning on other device it would go down. By go down I mean the Laptop would shut down or the hub would cycle on and off etc. It still would not throw the breaker though. Again the 110v has nothing to do with the 220v other than they both go to the same panel. | |

| Aug 22, 2017 at 17:04 | comment | added | user74603 | The circuits are totally separate other than they go to the same B panel. it's in an out build unrelated to my house. all other lights in the building work. I wired the 220v and the 110v was done years ago by an electrician. | |
| Aug 22, 2017 at 16:46 | comment | added | Tyson | @Harper sure, unless it's 4-wire equipment that also needs neutral because part of its not really 240v. | |
| Aug 22, 2017 at 16:38 | comment | added | Harper - Reinstate Monica | Do the two circuits share any wires? (Other than ground, we don't care if they share ground). Who wired this? Do you have any other loads in this house? Does the rest of the house work? @Tyson a lost neutral wouldn't affect 240V equipment, but a lost phase would. | |
| Aug 22, 2017 at 16:28 | comment | added | user74603 | I'm in Canada. I have not plugged anything else into the circuits; mostly because I don't have anything else that runs on 220v and I have not tried the lamp idea. I will give that a go on the 110v circuit and see what happens. I have the breakers turned off to both at the moment to avoid damage to anything else. | |

| Aug 22, 2017 at 15:51 | comment | added | CactusCake | Have you plugged a lamp into any of those outlets? Need to determine whether the issue is with the equipment vs the circuit. A wire tester can still show continuity even if the current is really low. A lamp will tell you if you're getting more than just phantom voltage. | |
