I had my breaker box open today and noticed that there is a buzzing noise when the Aqualink RS is turned on. The Aqualink RS is working normally, but I turned it off because it sounded abnormal to me. Any thoughts, I have an electrician coming tomorrow? I recently had a new Jandy VSP installed about a month ago if that helps.

Here's are some videos:

The breaker is bad.

You can see the arcing.

The breakers all need to be replaced with GFCI breakers.

The busbars might also be bad.

You can get a new busbar assembly.

Shut off power at the main breaker and verify no power at the subpanel with a multimeter.

Pull out all of the breakers and find the busbar model number sticker.

Do not do any work unless you are 100% sure that you know how to do it safely.

The correct part number is probably Siemens I0816ML1125CU, which should be on the part.

This looks like it would probably work.

It should be just 2 screws to remove the part.

As long as the screws are the same distance apart, it will probably work.

This comes with the metal box and you might be able to find the part without the box if you can find a part number on the part from the Hayward box or from the Siemens box.

It looks like (1) Tandem Double Pole Breaker, (1) 60 amp double pole, (2) 20 amp single pole, (1) 20 amp double pole.

What is the 60 amp breaker for?

Is that for a Heat Pump?

Can you describe what each breaker goes to?

It looks like (4) Double Pole Breakers and (2) Single Pole Breakers.

Plan to replace the busbar assembly and all breakers.

The blue light is high temp arcing.

Blue flames are typically between 2,500°C and 3,000°C (2,600°F and 3,000°F).

Melting point of copper: 1,984°F (1,085°C), so the metal will be damaged.

Thank you. This is definitely above my capabilities so will be bringing in a professional.

I think:
- Top Right (Aqualink RS)
- Bottom Right (Heater)
- Top Left (VSP and Spa Pump?)
- Bottom Left (Salt Water Chlorinator?)

NOTE The AquaPure® and PureLink systems are powered from the LOAD SIDE of the pool circulation pump relay.

This ensures that the cell only operates when the pool pump is energized.

The flow sensor serves as a secondary means to ensure there is sufficient flow for the cell to operate.

Looks kind of overloaded.

Maybe get two of these and install an extra Load Center to give you more breakers.

Pull out the busbar assembly from the extra load center to replace the existing busbar assembly

Note: Have an electrician evaluate and decide what the best choice is.
 
All pump circuit breakers need to be GFCI.
 
Some HVAC Equipment might be required to have GFCI protection.

2020 Code Language:

N 210.8(F) Outdoor Outlets. All outdoor outlets for dwellings, other than those covered in 210.8(A)(3), Exception to (3), that are supplied by single-phase branch circuits rated 150 volts to ground or less, 50 amperes or less, shall have ground-fault circuit-interrupter protection for personnel.

Exception No. 1: Ground-fault circuit-interrupter protection shall not be required on lighting outlets other than those covered in 210.8(C).

Exception No. 2: Ground-fault circuit-interrupter protection shall not be required for listed HVAC equipment. This exception shall expire September 1, 2026.

210.8(F) GFCI Protection for Outdoor Outlets:
Overview of a Life-Saving Technology
What is the change?
The 2020 edition of the NEC® now requires GFCI protection on residential outdoor outlets such as air conditioners. This
change would most likely require the standard circuit breaker supplying that outlet to
be a circuit breaker featuring GFCI protection.

Most likely, the Heat Pump will not require GFCI, but check with the electrician.

The heat pump breaker is old and I would probably replace it.

The blower should be on GFCI as well as all pumps.

The lights need GFCI, but they probably go through a GFCI outlet.

Maybe replace the light GFCI since it is probably really old as well.

You can go to a 15 amp single pole GFCI breaker for the light.
