Frequently Asked Questions
There are two main types of electrical distribution boards, first is electrical panels and second is solar LT panels.
- Electrical Panels: An electrical panel is also known as load center. This panel is a metal electrical service box that accepts the main power to the home and distributes electrical current to the various circuits within the home
- Solar LT Panels: Solar LT Panel is an electrical distribution board that receives power from an solar panels and distributes the same to various electronic devices and distribution boards. These types of panels are used in industries both for internal as well as external use.
In various industries, electrical consultants design electric distribution boards with distribution transformer. After which, they bus duct this board to PCC Panel for more distribution of electrical panels. Also electrical contractors supply MCC Panel and APFC Panel to enhance its functionality. Apart from this, when a client chooses to install solar power plant, we supply Solar ACDB and Solar DCDB Feeder Pillar and Junction Box along with synchronizing panels.
PCC is Power Control Centre. PCC Panels are those panels that supply or receive H.T. powers. Such panels are manufactured in a perfectly compartmentalized structure. There can be a provision of space heater, thermostat and backup protection if required by customer.
PCC panel is used for distribution and control of various electrical power source in the industry. Therefore, it is considered as the most important electric panel. PCC panel is a kind of distribution board in LT panels that can distribute power from the generation to production.
Furthermore, Accu-Panels is a leading PCC panel manufacturer in India.
MCC panel is Motor Control Centre panel that is used for motor control of various electrical power in the industry. MCC panel is a electrical control panel in LT panels that can easily control the motor from generation to production.
Moreover, Accu-Panels is a leading MCC panel manufacturer in India.
A motor control centre panel can include variable frequency drives, programmable controllers, and metering. It can also be the electrical service entrance for any building. To purchase MCC panel, contact us now. We offer a wide range of motor control panels at competitive pricing.

More questions buyers ask us
What does “IEC 61439 type-tested” mean and why does it matter?
A representative panel of the same design was physically tested at an independent laboratory (CPRI in Accu-Panels’ case) for short-circuit withstand, temperature rise, dielectric strength and degree of protection. “Compliant” or “as per IEC” without a test report does not prove the panel will survive a fault. Read our CPRI report explained at our CPRI report article.
What is the difference between PCC, MCC and PMCC panels?
A PCC distributes power from the transformer or DG set; an MCC starts, controls and protects motors; a PMCC combines both in one lineup for small and medium plants.
Which fault level (kA) should I specify?
The prospective short-circuit current at the panel incomer, calculated from transformer kVA and impedance. Accu-Panels offers 50 kA, 65 kA and 80 kA for 1 s busbar systems.
What are Forms 2b, 3b and 4b of internal separation?
IEC 61439-2 forms describe how busbars, functional units and terminals are separated. Form 2b separates busbars from units; 3b also separates units from each other; 4b additionally separates each unit’s terminals, allowing live maintenance.
Which IP rating do I need?
IP42 or IP54 for clean indoor electrical rooms, IP55 for dusty plants, IP65 for outdoor, washdown and solar sites (IEC 60529).
What is the typical delivery time for a panel?
2 to 4 weeks for standard AMF, changeover and distribution boards; 4 to 8 weeks for PCC and MCC panels; 6 to 12 weeks for drawout or intelligent MCCs, all counted from drawing approval.
Which documents are supplied with the panel?
Approved GA drawing, single-line diagram, schematics, bill of materials, routine test certificate per IEC 61439-1, warranty certificate and the type-test report reference.
Can we witness the factory acceptance test?
Yes. Dimensional check, BOM verification, functional and interlock tests, insulation resistance and the 2.5 kV dielectric test can be witnessed at our Ahmedabad works.
Do you offer drawout panels?
Yes. Drawout ACBs in PCC panels and fully drawout starter modules in MCC and IMCC panels, Form 4b.
What is an APFC panel and how is it sized?
An automatic power factor correction panel switches capacitor steps to hold power factor near 0.99. Required kVAr equals kW multiplied by (tan of the existing PF angle minus tan of the target PF angle); we size from your load survey. Range 20 to 3000 kVAr.
What is an 800 V LT panel?
A low-voltage switchboard rated for the 800 V AC output of string inverters in MW-scale solar plants. Every breaker, busbar and SPD is rated and type-tested for 800 V.
What is the difference between solar ACDB and DCDB?
The DCDB or array junction box protects PV strings on the DC side with gPV fuses, surge protection and a DC isolator; the ACDB protects, meters and isolates the inverter output on the AC side.
What warranty do Accu-Panels panels carry?
Standard workmanship warranty of 12 months from commissioning or 18 months from dispatch, whichever is earlier, with switchgear covered by the manufacturer’s warranty; extended terms are available on request.
Do you export electrical panels?
Yes. CE-marked panels are supplied to Africa and other international markets with seaworthy packing, export documentation and remote commissioning support.
How do I get a quotation?
Send your single-line diagram, load or motor list, fault level and site conditions to sales@accupanels.com or WhatsApp +91 63588 01780; a techno-commercial offer with GA drawing follows within one working day for standard panels.
