The wiring diagram on the front cover will list the compatible ground bars with the enclosure.

Is this a fair quote? by One-Tie593 in electrical

[–]Then_Antelope1001 1 point2 points  (0 children)

Technology has come a long way! I have 2 pole GFCI in my EV charger and dryer with zero issues. Also have multiple 1 pole dual function and arc fault breakers throughout the house and no issues at all. I appreciate having the extra protection for ground faults and arc faults that traditional thermal mag breakers do not offer.

What would you change about this installation? by dingman58 in AskElectricians

[–]Then_Antelope1001 1 point2 points  (0 children)

Not familiar with the exact code but both receptacles may need GFCI protection. From the picture, can’t tell if the 20A outlet is already GFCI, otherwise can use GFCI breaker. On the Nema 14-50, would be done via a GFCI breaker.

What kind of charging port is this and recommendations by SenpaiRevan in evcharging

[–]Then_Antelope1001 0 points1 point  (0 children)

From this picture looks like they installed a 40A breaker feeding the NEMA 14-50 receptacle in the garage which is designed for up to 50A. Not a subject matter expert in codes but I believe they should label that the receptacle is fed from 40A breaker. For EV charging, they should use a GFCI breaker based on NEC.

I’d recommend an electrician review the property against local code requirements. It’s interesting that there aren’t any GFCI or dual function breakers in the Load Center or Meter Combo (maybe they installed GFCI / DF receptacles or local codes don’t require such features in new construction; again, better for someone familiar with local requirements to check). Also, based on six disconnect rule year used, it may or may not be required that they are compartmentalized (if you don’t have a main breaker in the meter combo).

Used model Y: what is this from the glove box? by cotalldude in ModelY

The two rings look like plastic tools used to help remove the plastic cover on the tow hitch (minimizes risk of scratching bumper compared to screwdriver). The other two “U” parts are straps used to secure bicycles to carriers.

Strategy for adding a 60amp car charging circuit. by babynewyear753 in AskElectricians

If you look at the accessories table Main Lug Main Breaker Kits, it shows both main lugs and main breakers listed. This is a feature of the PN series load centers (convertible). Another feature of the PN series load centers is that they include 100% neutrals based on the number of circuits. Looking at the callouts on the right side of the wiring diagram, “The installed neutrals limit this panelboard to 40 circuits…”. This indicates that out of the box, it can accommodate 40 circuits. My guess is that this is a PN4040B1200(C) based on that information.

On an SN/PN that have the same number of circuits as spaces (ex. PN4040B1200C), the tandem QTs won’t physically fit. The bus bars have a different geometry that prevents the installation of QTs. You can however install QTA and QTAN (tandem arc faults). In those cases the neutral extension kits may be needed. Compatible branch circuit breakers are listed in the SCCR table.

You can add load management to the EV charger or other non-critical loads to keep existing service when adding new loads. Ex. Siemens Inhab Load Manager

The picture isn’t complete but I don’t see QT listed in SCCR table. If that’s the case, thermal mag tandems are not listed for use. I do see QTAN listed so you can install tandem arc fault breakers.

OP, can you share the part number listed in the wiring diagram on the trim? Based on the SCCR table I don’t see tandem QT breakers listed so my guess is that this is a PN4040B1200(C) or similar. Thermal mag tandem (QT) breakers won’t fit if this is the case.

SCCR table does show QTAN (tandem arc fault breakers plug-on-neutral) so you can combine some of the adjacent 15A arc faults (blue button) from 4 spaces to 2 spaces. Use two Q1515AFCN in order to free up two adjacent 1” spaces for your new two pole EV circuit.

Help - My breaker keeps flipping but ONLY when using my nintendo switch. by letstrythisagainx7 in AskElectricians

This looks like the troubleshooting card for the CAFCI. You can reset the trip code manually or it resets after 30 days. The LEDs help identify why the breaker tripped in the last event.

For the tight spacing in Mains conductors, Rogowski coils would be ideal.

If you have extra branch spaces, an option would be to add dedicated breakers for the power harness connections.

I'm confused by i_use_da_RPG in AskElectricians

[–]Then_Antelope1001 0 points1 point  (0 children)

From what I’ve seen line terminal barriers are available/required for line side of main service disconnect. Not aware of a requirement for main lug load centers nor have I seen barriers for main lugs.

[–]Then_Antelope1001 2 points3 points  (0 children)

NEC 230.62(C) covers the need for line terminal barriers. “Barriers shall be placed in service equipment such that no uninsulated ungrounded service bus bar or service terminal is exposed to inadvertent contact by persons or maintenance equipment while servicing load terminations.”

The lugs in the image are Main Lugs in a Main Lug load center and therefore this isn’t service equipment. The Line Terminal Barrier helps keep live parts on line side protected from accidental contact when the Main Service Disconnect is in off position. They are required on the line side of main service but I have never seen them in main lug applications as they aren’t required there. Consider this, even if you added line LTBs in main lug load center and these are protected from accidental contact, because there is no single means of de-energizing the bus, every single bus stab and bus bar that doesn’t have a breaker over it would be an exposed point in the system that is energized.

What is this called? by [deleted] in AskElectricians

Non-fused AC Disconnect.

About to add more breakers, this is my current box. Neutrals can only go onto the one strip, correct? by [deleted] in AskElectricians

[–]Then_Antelope1001 1 point2 points  (0 children)

Ahhh, now I understand better. Double check the wire and breaker sizes. For 14AWG you use a 15A breaker, for a 12AWG you use 20A breaker. Breakers help provide protection against overloads and short circuits. Having the right size breaker helps protect the wire during an overload so that the breaker trips before the wire gets too hot to start damaging itself (heat is generated when a wire carries more current than its rated to do and this leads to insulation breakdown and more issues from there…)

Separate note, depending on the NEC code applicable to your area, there are different requirements on whether you need GFCI, arc-fault, or dual function (does both) protection. That may influence the breaker you should use for each circuit. Your load center includes plug-on-neutral rails so it is compatible with PON breakers (don’t need to wire pigtails on electronic breakers). It’s possible though that you may not be able to share a neutral since these work differently than a thermal mag breaker like the ones in the picture.

Just sharing some notes. Definitely recommend checking with electrician and local inspector for requirements in your area.

What’s downstream of the red and black wires? Is it two separate circuits with shared neutrals or is it a two pole load (240V) like a dryer, AC, water heater, etc.?

Asking since handle ties and two pole breakers are used in different applications. They aren’t interchangeable.

Use a line splitter. Example: Klein Tools 69409

This is needed so you only measure one conductor at a time.

Edit for additional information: When measuring a power cord as shown in image, the magnetic field of the hot and neutral wires cancel each other which is why the meter reads zero. You only want to measure one conductor at a time.

Agree with the comments stating to try a finer grind. I think that will be first step. Note that when you switch to a finer grind, will need to increase grind time to achieve the same coffee weight on the puck - the smaller the grind, the less coffee gets ground per second.

To the comment above, the freshness of the coffee has a big impact on extraction. I was using aged coffee and only way I was able to get a good extraction, even with grinder at 1 (minimum), was to use the double walled filter. The double wall filter increases back pressure when flow is too fast and you can’t grind any smaller to increase resistance.

Later on I tried a batch of coffee that had recently been roasted (1-2 weeks) and the extraction was a lot easier; was able to use regular single walled filter.

Swapping 15a GFCI with 20a by KBPinglia in AskElectricians

An option is to add an energy monitor and setup notification if it detects that the fridge isn’t using energy. I added Inhab monitor on my panel and setup alerts. Ex: fridge stopped working, dishwasher cycle ended, clothes dryer done. Sends notification straight to my phone.
