Lighting circuits (UK) are fused at 15A. If in doubt, check the fuse/MCB. Unless the 7A device is lighting, connecting it would be illegal in the UK. Don't forget anything else on the same circuit.

It depends on the rating of the circuit. Standard lighting circuits in households are typically 15 or 20 amps. If your circuit is 15 amps, then 7 amps should be fine. However, if it's a 20 amp circuit, 7 amps should still be safe but you need to be cautious about adding more loads.

What is the continuous current draw on a 20 amp circuit breaker?

The continuous current draw on a 20 amp circuit breaker should not exceed 16 amps to allow for a safety margin. This helps prevent overheating and potential tripping of the circuit breaker. It is important to follow the manufacturer's guidelines and not overload the circuit.


How many amps equal 1 circuit?

It depends on the capacity of the circuit. A typical residential circuit in the US is rated for 15 or 20 amps.


Will using an outdoor extension cord to a shed with 14-2 gauge wiring cause an overload with the circuit?

To start with a #14 conductor is rated at 15 amps. An overload is any current rating above what the conductor can legally carry. So to answer the question, as long as the amperage stays below the conductor rating of 15 amps no overload will occur. Depending on the length of the cord to the shed it could cause you some low voltage problems because as the voltage drops due to line loss the current will go higher. This is especially true is a motor is connected to the circuit in the shed.


Is it safe to use a 20 amp circuit for lighting runs?

Yes : but in a residential case a 15 amp circuit would be better


How big of a load does a 30 amp plug handle on a 40 amp circuit?

A 30 amp plug should only be used on a circuit that is rated for 30 amps to prevent potential overload and safety hazards. Plugging a 30 amp load into a 40 amp circuit could lead to overheating of the wiring and potential fire hazards. It is important to always match the plug amperage with the circuit rating to ensure safe operation.

Function of a breaker?

The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.


What is the maximum amperage capacity of a 60A breaker and how does it affect the electrical circuit it is protecting?

The maximum amperage capacity of a 60A breaker is 60 amps. This means it can handle up to 60 amps of electrical current before tripping and shutting off the circuit. It protects the electrical circuit by preventing an overload of current, which can cause overheating and potentially start a fire.

What is the maximum load on an outlet line?

The maximum load on an outlet line is typically around 15-20 amps, which is the standard capacity for most household outlets. Exceeding this limit can cause the circuit to overload and potentially lead to a fire hazard. It is important to be mindful of the electrical devices and appliances that are plugged into an outlet to prevent overloading.

Is a dedicated circuit for floor outlets necessary?

It depends on what the amperage of the connected load is. If it above 10 amps on a 15 amp breaker then make is a dedicated circuit. If it is used for lamps in the center of a room, then the floor outlet can be incorporated into the regular lighting and receptacle circuit.
