Eaton

A: Two wiring styles, same protection. The pigtail versions (BRN115AF at 15A, BRN120AF at 20A) carry a white neutral wire you land on the panel neutral bar, and they work in any Type BR loadcenter. The plug-on neutral versions (BRP115AF at 15A, BRP120AF at 20A) pick the neutral up off a neutral bus bar built into the panel, so there is no pigtail to route, but the loadcenter has to be a BR panel equipped for plug-on neutral. If you are replacing a breaker in an older BR panel, order the pigtail.

A: Only if the panel is an Eaton Type BR loadcenter. These are plug-on breakers built specifically for Type BR bus, so they will not seat correctly in a Type CH panel or in another manufacturer's loadcenter. Check the label inside the panel door for "Type BR" before ordering.

A: It needs both. A GFCI breaker works by comparing current on the hot and the neutral, so the circuit neutral lands on the breaker itself, not on the panel neutral bar, and the breaker's own pigtail goes to the neutral bar. Miss that and the breaker trips the moment you energize it. The BRN GFCI ships with that pigtail attached.

A: No. The CH three-pole breakers are built for Type CH loadcenters only. Type CH and Type BR use different bus and mounting arrangements, so a CH330 or CH350 will not seat correctly in a BR panel. Check the label inside your panel door for the accepted breaker type before ordering.

A: Top or bottom, both are supported. The mounting method on the ED kit covers top and bottom positions, which matters when the service feed enters from below and you do not want to run the conductors the full height of the enclosure to reach a top-fed main.

A: The QBHW is a bolt-on breaker, not a plug-in. It fastens to the bus with screws rather than clipping onto a stab, so it needs a panelboard with bolt-on bus provisions. If the panel you are working in takes plug-on breakers that snap over a stab, a QBHW will not seat in it. Bolt-on is standard on commercial and industrial panelboards, which is where this breaker belongs.

A: Main lug means no main breaker in the panel. The feeder lands directly on the lugs and overcurrent protection has to come from upstream, typically the main breaker in the service equipment or a feeder breaker in the panel ahead of it. That makes the CH main lug the right choice for a subpanel: a detached garage feed, a shop, a tenant panel fed from house main. If this is the service disconnect at the meter, you want a main breaker loadcenter instead.

A: Five metering sockets, each rated 125A at 120/240V, single-phase in and single-phase out. That covers five separate tenant services off one assembly, which is the typical setup for a five-unit apartment building or a small strip of light commercial suites. If you need more than five positions you need a different socket count, not an add-on to this unit.

A: The lever bypass lets you shunt current around the meter socket jaws so the meter can be pulled and reset without dropping power to the load. For a property manager with occupied units or a retail tenant, that means meter swaps and testing happen without a service outage. It is the feature most commercial utilities require on 200A single-position service.

A: No fuses. The ACD60R is a non-fusible pullout, so the pullout block simply breaks the circuit when removed and there is nothing to replace when it is put back. Overcurrent protection has to come from upstream at the panel breaker. If your condenser nameplate calls for maximum fuse size rather than a maximum breaker, you want a fusible disconnect instead of this one.

A: Both Eaton DPF pullout disconnects are built for outdoor equipment: the enclosure is NEMA 3R galvanized steel, which is the rating for rain, sleet and ice exposure on an outdoor wall or condenser pad. Rated 120/240V, with a 10 kAIC interrupt rating. Pick DPF221R for a 30A unit and DPF222R for 60A, matching the amperage on the equipment nameplate.

A: No. It is a fusible switch, meaning it has the Class H fuse clips, but fuses are sized and bought separately to match the load and your overcurrent coordination. Order fuses rated to the switch amperage: 30A, 60A or 100A depending on the build.

A: Both are available on the DH heavy-duty line, along with a fusible-with-neutral version. Go fusible when the switch has to provide the overcurrent protection itself, which is typical at a service disconnect or where a motor branch circuit needs its own fuses. Go non-fusible when the circuit is already protected by a breaker upstream and the switch is only there as a local means of disconnect at the equipment, the usual case for an AC unit or a rooftop motor within sight of the machine. Fusible with neutral is what you want when the circuit carries a neutral you need to land and isolate as well.

A: That is decided by the available fault current at the panel, not by the breaker. The Pow-R-Xpress kit is offered in 35 kAIC and 65 kAIC. If the utility transformer and conductor run put more than 35 kA of available fault current at the panelboard, the 35 kAIC kit is not a legal install and you need the 65. On a long feeder run off a small transformer, 35 is typically plenty. Take the number from the fault current study for that panel location.

A: The CHMIKCSR fits Eaton CH load centers that use a CSR or CSH main breaker, in three-phase configuration, rated 225A. If your CH panel has a different main breaker type (or a main lug setup with no breaker to interlock), this kit is not the one. Match the main breaker designation stamped on the breaker before ordering.

A: The main breaker is part of it. This is a Type KD MCB unit, meaning the meter position and the main circuit breaker protection are combined in one module rather than metering only. If you want a meter socket with no main disconnect, that is a different piece of equipment.

A: It's a transformer rated, instrument rated socket, so it is not self-contained. The 20A rating is the instrument circuit rating, not the service load. You feed it from current transformers (and potential transformers where the utility requires them) on the primary side, and the socket carries only the CT secondary and voltage circuits to the meter. If you're metering a service directly without CTs, you need a self-contained socket instead.
