    Breakers and buss appear to be overheating on a long-term basis

    My 125A/240V service meter-main/load center is about ten years old, an Eaton MBE1224B125BTS, which (aside from the main common-trip 125A pair) has 12 buss lugs available. Mainly it's used for light residential loads. But since I also do some hobby-level shop fabrication metal work, I run a 50A...

    Chint breakers

    Hello everyone, I’m looking to understand the key differences between chint breakers and Schneider breakers. I’ve noticed that both brands are available for a project I’m working on, and I’m trying to make an informed decision. Could anyone provide insights into how these two brands compare in...

    Possible to tell which Murray replacement to get without removing the breakers (w/pics)?

    I need to replace two AFCI breakers on our main circuit panel. I have replaced and added breakers to our sub-panel several years ago. When I did so, it was convenient to leave that panel unpowered for more than a few minutes, so I was able to take an existing Murray breaker with me to ensure...

    Interlock switch, not powering all of my breakers

    I have hooked up a 30 amp interlock switch to my main panel run off my generator. However, only my light switches work none of my plug-ins have any power. Any input would be helpful. Thanks.

    RCD trips with all load breakers open

    My circuit panel has two banks of breakers, each bank protected by an RCD. One of these RCDs has been problematic in that it trips intermitantly. A few months ago it became so frequent that we had the RCD replaced. It would trip regardless of what load breakers were shut or open. No fault could...

    Safe/prudent to replace AFCI breakers with CAFCI breakers?

    I am going to be replacing two AFCI breakers after a lightning strike in a house built in 2003. I will be bringing the breakers with me to ensure I get the same brand and specs, but I’m wondering if it would be safe and prudent to replace them with CAFCI breakers (assuming I have a choice)...

    Lightning strike damaged 2 AFCI breakers. What to check after replacing breakers and testing outlets

    Background Two weeks ago, lightning struck a tree in our yard. Many circuits tripped and several electronic devices failed. There was a strong smell of ozone/electrical burn throughout the house that has since dissipated. Two AFCI breakers are still problematic. Both serve bedrooms (hence AFCI)...

    Dehumidifier trips breakers on one panel but not another

    Hi everyone. I have a basement that was finished years ago. The basement is on a separate panel than the rest of the house. For years I've had several dehumidifiers die various deaths in my basement. I thought it was just bad luck, but now I'm not so sure. My latest dehumidifier started tripping...

    Mixing of circuit breakers

    It's all coming out anyway so it's an acedemic question. Would a Bill consumer unit be comparable with Eaton breakers? An Eaton main switch and mcbs are installed so height differences won't be a problem. I'm changing it for full rcbo with spd board anyway.

    How to map circuits when some breakers are quads

    I have a question about mapping circuits in a single family home. I recently had my panel upgraded to an Eaton 2040 panel, and the electrical contractor who did the work did not label things very clearly, so my plan is to relabel all circuits from scratch. As part of the upgrade he installed 4...

    Were these breakers tampered with?

    Over the holiday period my partner returned home to her apartment with no power. None of the internal breakers in the consumer unit had tripped and so she was unsure what to do. She called an electrician who took the cover off the consumer unit and then showed her these singed breakers across...

    underfloor heating and tandem breakers

    Hi, this is a bit complicated. We installed two separate underfloor heating system in our downstairs area. One at 240V and according to the manufacturer at 11.9Amps. The other one also at 240V and 9.7Amps. Because of the lack of space in the 200Amp panel, we connected them to two separate...

    Is electric panel dangerous?

    Electrician saw white on breakers (see pic) and says I must replace whole panel with a larger one because it’s overloaded and dangerous. Does this sound right?

    Breakers tripping other breakers

    Asked my electrician this question but he never experienced anything like it and did not have any real suggestions or tests. My daughter bought a new condo. We found out that when you switch one breaker off (I'll call it Breaker1) and then turn it back on it trips another breaker (Breaker2) ...

I have an old fuse wire fuse board on a wooden plate with no rcd or breakers, I had assumed this would be a C1 or C2 but this came back as a C3.
